Some bedfellows are pure fantasy.

Sonja Morgan was seemingly caught in a lie on Tuesday’s episode of “The Real Housewives of New York City” after bragging to her gal pals that she’d slept with a sexy younger model named Dylan.

After Morgan, 57, told castmates Ramona Singer and Luann de Lesseps that she could “hardly walk” after her hot night, Singer, 64, later got some scoop that the evening may not have been as intimate as Morgan claimed.

“Why is Sonja making up stories? Why does she want to say that she had hot sex with some hot guy all night when she actually passed out in his bed and someone had to go get her?” Singer said in a confessional. “I don’t know what Sonja’s trying to prove.”

Singer said she was told that while Morgan did go back to Dylan’s hotel room with him, his girlfriend was there too, and all three of them hung out before Morgan “passed out drunk” on the bed.

Dylan also posted video evidence to his Instagram Story of the trio together.

Singer said that Dylan ended up having to call their mutual pal Hank to take Morgan home at 2 a.m.

“He was a very good lover,” Morgan told her co-stars, leading Singer and de Lesseps, 56, to confront their pal with their knowledge that Dylan has a girlfriend.

An embarrassed-looking Morgan then hid from her two close pals and shut the door, while they yelled, “Busted!” from the other side.

But Morgan didn’t back down from her steamy tale, telling co-star Leah McSweeney she and Dylan had a “fling” even though his girlfriend was there.

“All of the sudden this girl comes out of the bathroom, and I’m like, ‘What the f–k?’” Morgan said. “I know I have this date coming up to see marriage-material guy so it was, like, a fling.”

She added, “I was there for the d–k.”

“The Real Housewives of New York City” airs Tuesdays at 9 p.m. ET on Bravo.
