The chart-topping star got glammed up to go and see her Wicked co-star boyfriend perform on Broadway on launch night of his new production Spamalot

Ariana Grande stepped out to support boyfriend Ethan Slater at the opening night if his new Broadway musical.

The chart-topping star was snapped stepping out of an SUV as she arrived to watch her beau perform in Spamalot on Thursday night. Ariana, 30, looked effortlessly glamorous as she turned up to the event, wearing a black velvet bandeau dress with sheer gloves and pearl earrings.

She wore her long blonde hair tied back in a ponytail and added a striking makeup look with pink eyeshadow and scarlet red lipstick to complete her outfit. Ethan meanwhile was spotted entering the building to prepare for the show earlier in the day.

Wicked co-stars Ariana and Ethan have attracted much attention over the relationship, which comes ahead of the film adaptation of the Wizard of Oz prequel being released in two parts. It’s been reported that the pair are now living together in New York City.

The apparent romance is said to have come following the end of their respective previous relationships. It was reported in July that Ethan had filed to divorce his estranged wife Lilly Jay. It was reported last month that Ariana and her estranged husband Dalton Gomez had also filed for divorce.

A source recently told US Weekly that Ethan has “informed his friends and soon-to-be ex-wife Lilly Jay that he’s living with Ariana full-time in New York. They’re really happy and really good for each other,” they added. “All of her friends love him.”
