Fans assumed she was primarily there to support Slater, who played The Historian and Prince Herbert in the production.

"She has seen it during tech rehearsals," an anonymous attendee told People. "She was so sweet last night, taking pictures with fans and gushing about how much she was enjoying the performances. She's a theater kid at her core, so you see she really feels at peace being around Broadway."

Before becoming a pop star, Grande got her start on Broadway as a teen in "13: The Musical." She attended the "Spamalot" preview with her former "13" and "Victorious" costar, Liz Gillies, who shared a selfie with Grande on her Instagram story.

January 12, 2024: Grande mocks people who scrutinize her sex life in the new single 'Yes, And?'

"Yes, And?" was written by Grande, Max Martin, and Ilya Salmanzadeh for Grande's forthcoming album.

In the song, Grande takes on critics of her body and relationship, with the most relevant lyrics appearing in the bridge: "Your business is yours and mine is mine / Why do you care so much whose **** I ride?" (The censor is Grande's own.)

The "Yes, And?" music video doubles down on this theme. It shows Grande performing the song for her biggest critics, who, by the end of the song, are persuaded to abandon their haughtiness and dance along with Grande.

March 8, 2024: Grande releases her album 'Eternal Sunshine,' which may contain references to her new boyfriend

Amid several breakup songs on Grande's seventh studio album, she sings about finding new love.

"I found a good boy and he's on my side / You're just my eternal sunshine," she sings in the title track, drawing a distinction between her new man and her ex. (Although Grande hasn't identified any muses for "Eternal Sunshine," the information we have about her love life would indicate these lyrics are about Slater and Gomez, respectively.)

"Supernatural," "Imperfect For You," and "Ordinary Things" also allude to a recently sparked romance ("Nothing else felt this way inside me," "We crashed and we burned / Now I just can't go where you don't go," "There's never gonna be an ordinary thing as long as I'm with you").

Notably, the two-song sequence "True Story" and "The Boy Is Mine" addresses Grande's reputation as a "villain" in the public eye — but filtered through a satirical, tongue-in-cheek lens.

"It's like, 'OK, I'll play the bad girl, here's your bad girl anthem,'" Grande told Zane Lowe. "That's why they're in that order in the tracklist."

September 30, 2024: Grande defends Slater and their relationship against 'disreputable evil tabloids'

Grande addressed the rumors about her love life in her Vanity Fair cover story (without mentioning Slater by name).

"It definitely doesn't get any easier, seeing some of the negativity that was birthed by disreputable tabloids. Of course, I went through a lot of life changes during the filming of this movie. A lot of people that were working on it did," Grande said, referring to "Wicked."

Grande also disavowed the negative perception of her relationship with Slater, which she said was created by the media — though, again, she didn't clarify any specifics, telling the magazine she "will never go into certain details."

"The most disappointing part was to see so many people believe the worst version of it," she said.

"There couldn't be a less accurate depiction of a human being than the one that the tabloids spread about him," Grande added of Slater, alluding to rumors that he left his wife and child to be with her.

"No one on this Earth tries harder or spreads themselves thinner to be there for the people that he loves and cares about. There is no one on this Earth with a better heart, and that is something that no bullshit tabloid can rewrite in real life."

October 30, 2024: Slater confirms he 'fell in love' while filming 'Wicked'

During an interview with GQ, Slater was asked about his new relationship.

"You also fell in love making this movie," reporter Eileen Cartter said to him. "Can you tell me a little bit about what that was like?"

"Yeah," he replied. "That's a really sweet question. That's really nice of you to ask. That's a really sweet question."

"Obviously, it was a really super big year," he continued, "and I think there was something that was really difficult about things in your private life being commented on and looked at by the public. There were a lot of big changes in private lives that were really happening, so it's really hard to see people who don't know anything about what's happening commenting on it and speculating, and then getting things wrong about the people you love. So just to address that part of it, that feels really hard."

Despite the rumors about his love life, however, Slater said it was "an amazing year and a really beautiful thing." He also praised Grande's acting chops and comedic timing.

"I'm just really, really proud of Ari and the work she's done on this," Slater said, referring to her role as Galinda. "She's poured herself into it. I'm really proud that I got to be there for that part of it, and I'm really excited to be there for this next step of it when the world gets to see the amazing thing that she did."

Grande signaled her support by sharing GQ's photos of Slater on her Instagram Story.

She also shared a link to the interview, calling it "a beautifully written piece about an unfathomably beautiful human being."

Grande liked the post and commented with three cupid-heart emojis.

In the weeks following, he shared two more photos with Grande from the "Wicked" set (one on November 29 and another on December 5), both showing the costars in their Shiz University costumes.

December 19, 2024: Lilly Jay publishes an essay that unpacks her sudden public divorce

Jay's first-person essay ran in The Cut under the headline, "How Does My Divorce Make You Feel?"

The piece explores Jay's career as a clinical psychologist, her desire to remain anonymous for the sake of her patients, her new life as a mother, and how the "sudden public downfall" of her marriage complicated all three.

"I really never thought I would get divorced," Jay writes. "Especially not just after giving birth to my first child and especially not in the shadow of my husband's new relationship with a celebrity."

Although Jay never names either Slater or Grande in the piece, she refers to "a tabloid drama in which I play the role of a voiceless ex-wife."

Jay also reveals that she "confidently moved to another country with my 2-month-old baby and my husband to support his career," confirming that she and Slater were still together when he began filming "Wicked" in England.

Although Jay is still grappling with the ripple effects of their breakup, she praises Slater's commitment to co-parenting their child.

"While our partnership has changed, our parenthood has not. Both of us fiercely love our son 100 percent of the time, regardless of how our parenting time is divided," Jay writes. "As for me, days with my son are sunny. Days when I can't escape the promotion of a movie associated with the saddest days of my life are darker."

Grande and Slater did not immediately respond to Business Insider's request for comments.
