Ariana Grande and her rumored beau, actor Ethan Slater, didn't hide their romance on the set of "Wicked."
On Aug. 3, DailyMail.com reported that, according to a source, Ethan and Lilly Jay — his wife of five years — were still together when his "affair" with the pop star began.
"They were sloppy on set," the source said. "They were seen being all over each other while he was still supposedly happily married to Lilly."
The insider claims Ariana and Ethan were somewhat reckless with their relationship in public on several different occasions.
"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]," the source claimed.
A different source, however, insists that the new duo didn't begin dating until they were both single.
It's unclear when exactly Ethan and Lilly separated, though he publicly honored her on Instagram while marking Mother's Day in May. At the time, he called her "the most loving caring and wonderful mom/person in the world."
Yet another DailyMail.com source shed some light on Lilly's awareness of her husband's affair: "There was a period when they were all going to try and work on their marriages and put the whole thing behind them," the insider claimed. "She thought they were happy. But that did not work out [because Ariana and Ethan] kept the affair going despite [that]."
There have also been reports that Ethan and Lily double dated with Ariana and her estranged husband, Dalton Gomez, before both marriages imploded.
Ethan filed for divorce last week.
