“So Pete Davidson was engaged to the sexy & talented @ArianaGrande and is now dating the beyond stunning @KateBeckinsale?” Frankel wrote.
“So I guess it’s clear that he shoots diamonds out of his penis?”
Responding to a fan who then wondered how women “keep falling” for the comedian, Frankel responded, “He is probably nice & funny & sensitive which women like. Cute and sweet. And the diamond D doesn’t hurt I reckon.”
The Saturday Night Live comedian, 25, has been linked with Kate, 45, ever since the two were spotted hitting it off at a Golden Globes party in early January.
As PEOPLE previously reported, the two talked intently for most of the night there, keeping their focus on each other even while mingling with Pete's close friend Machine Gun Kelly, Isla Fisher and Sacha Baron Cohen.
Eventually, the other members of the group wandered off, and Pete and Kate continued to chat. One source said they cuddled at the party as well.
On Friday night, the pair was seen holding hands as they left famed music and comedy venue Largo at the Coronet in West Hollywood, California, where Pete was performing a stand-up show.
Pete's latest set featured some material from his Jan. 12 show at the Tarrytown Music Hall in New York — including a joke about ex-fiancée Ariana Grande‘s infamous comment about the size of his penis, which he called a “mean” but “also genius” move.
“I don’t like that she talked all that s— for my penis,” Davidson joked in January.
“Everything is huge to her,” he continued. “Why would she tell everyone that I have a huge penis? So that every girl who sees my d— for the rest of my life is disappointed.”
