Meghan King Edmonds is leaving little to the imagination.

The former "Real Housewife of Orange County" star took time out of her coronavirus quarantine to lip-sync and dance to Beyoncé's hit song "Single Ladies" just days after her ex-husband, Jim Edmonds, revealed he has a new girlfriend.

The mom-of-three, 35, wore nothing but a pillow as she participated in the now-viral "Pillow Challenge" on Tik Tok.

Meghan alleged in January during her podcast “Intimate Knowledge” that Jim was in Cabo San Lucas with the woman and described her as a “friend” of the former couple.

Jim Edmonds denied the claim at the time and said it was “completely false.”

“I was invited to a surprise birthday party this weekend for one of my best friends and decided to bring a date. There is no affair going on here. It has been a plus one for the weekend,” Jim, 49, told Us Weekly at the time. “The woman I am in Cabo with is not her friend. They have not spoken in over three years.”

Meghan King Edmonds also broke down into tears during the episode as she detailed her marriage.

“We were newlyweds and trying to have fun and he wanted to have a threesome. … I’m shaking right now. I never even told anyone that I had a threesome because it just felt like … something I wasn’t proud of,” she said. “And now this is the woman he’s with? … It’s just so hurtful in so many ways. And I want to share it because I don’t want to feel shame in the decisions that I made.”

Jim Edmonds quickly responded to his ex-wife’s claims on the same day, and maintained that his marriage to the reality star “is and has been over.”
