Karen wants to have her cake and eat it, too.

In a sneak-peek video for the upcoming Season 4 installment of ABC’s “Mistresses,” Karen (Yunjin Kim) reveals to her friends that her manny, Robert (Jerry O’Connell) isn’t just taking care of her daughter. He’s also taking care of Karen … sexually.

Karen’s shocking secret comes out in episode 3, titled “Under Pressure,” while Kate (Tabrett Bethell) is swiping through a dating app on her phone. Harry’s (Brett Tucker) newly single sister is searching for a rebound — encouraged by Joss (Jes Macallan) — following her heartbreaking breakup. As Kate is searching for potential suitors, she stumbles upon Robert’s photo.

“Oh my God! That’s my manny!” Karen shouts when she sees the photo of her handsome employee/lover. But April (Rochelle Aytes) doesn’t seem to understand why Karen is so shocked. After all, Robert is on the market … isn’t he?

“Well, I don’t know how available he is anymore. We had sex last night. And this morning, too!” Karen says, unveiling her secret with a smile.

But her friends don’t share the same reaction to Karen’s manny romance.

“You’re sleeping with your manny? Is that such a good idea?” Kate asks while Joss chimes in, questioning Karen’s plan.

“I can have my manny and sleep with him, too,” she says slyly. But Karen’s plan will go awry in the forthcoming episode when Robert begins to blend his roles as a manny and a lover.
