Ariana Grande and her boyfriend Ethan Slater did not hide their apparent feelings for each other while filming Wicked, allegedly packing on PDA despite still being in their respective marriages.

“They were sloppy on set,” an insider shared about the newfound couple, RadarOnline.com has learned. “They were seen being all over each other while he was still supposedly happily married to Lilly [Jay].”

Cast members were claimed to have noticed their touchy-feely banter even when they were attending other events.

“They were seen making out at a pub in Hampstead, and they were all over each other at Michelle Yeoh’s Oscar party [in March],” DailyMail.com reported.

Tipsters even alleged that Ariana and Ethan went on “multiple” double dates with her now-estranged husband,

Dalton Gomez, and Ethan’s wife of four years, Lilly, whenever they visited their spouses. Meanwhile, they apparently carried on their own courtship.

“Lilly and Ethan also met Ariana’s family together, including her mom and her brother,” they said.

Other insiders have denied the timeline and said Ethan and Ariana didn’t start seeing each other romantically “until after he had separated from Lilly.” Reports claim the No Tears Left to Cry singer and Gomez have been separated since January.
