The “Positions” singer, 30, was in the crowd at the St. James Theatre in New York city for the performance of the Monty Python musical revival supporting none other than her boyfriend who plays a variety of roles in the comedy.
In the outing, Grande was seen wearing a modern strapless long black dress that ended just below her knees. The songstress paired the look with black sheer gloves and stockings.
Grande even carried a small leather black drawstring bag in her hands.
The singer was seen with her iconic slicked back ponytail and pearl drop earrings. Sporting a bright red lip, Ariana was also seen with her more natural makeup aesthetic.
Grande was photographed waving at fans while clasping her purse and even signing albums and photos for fans with a Sharpie pen while she exited the theater.
The star was escorted by several security guards as she made her to her own car.
The occasion did not see Grande and Slater walk the red carpet together as she avoided the press line. Prior to her arrival, Slater, 31, had posed for photographs on the carpet in a black suit and tie with a white button-down shirt.
The star was later joined by his costars Jimmy Smagula, Taran Killam, Leslie Kritzer, Nik Walker, Christopher Fitzgerald, Michael Urie and James Monroe Iglehart, for a group photo.
Back in October, the singer was seen cheering on the show’s first performance. Ariana was seen in the audience in an Instagram video shared by an attendee.
A source told PEOPLE at the time that Grande was been a “big supporter” of the production and had “plans to go again.”
“She has seen it during tech rehearsals,” the insider shared. “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.”
Grande also got her start on Broadway when she starred in Jason Robert Brown’s short lived 2008 musical 13.
The production marks the first time since Spamalot returned to Broadway since its debut in 2005.
Based on the beloved 1975 film Monty Python and the Holy Grail, Spamalot follows King Arthur and the Knights of the Round Table on their quest for the Holy Grail. Tim Curry, Hank Azaria, David Hyde Pierce, Christian Borle and Sara Ramirez were among those who starred in the original production.
Grande and Slater met on the set of the upcoming movie adaptation of Wicked, and developed a romance offscreen. Slater, who made his Broadway debut in SpongeBob SquarePants: The Broadway Musical, will play Boq, the love interest of Elphaba’s sister Nessarose who is infatuated with Glinda (played by Grande).
The pair’s relationship, which was first confirmed by What’s Trending in July, began after her separation from husband Dalton Gomez and Slater’s separation from wife Lilly Jay. Last month, Grande and Gomez, 28, settled their divorce just weeks after filing, following two years of marriage.
