Kate Beckinsale Is Helping Pete Davidson Survive His Big Breakup

Pete Davidson has learned the hard way that you can go home again. 

This summer he was riding high, living it up at the $16 million 4,000-square-foot loft fiancée Ariana Grande had shelled out for in New York City's Chelsea neighborhood. 

Equipped with five bedrooms but no furniture, save for some six bean bag chairs, as Davidson shared with GQ, it was the perfect spot to play house and a pretty sweet deal for the Saturday Night Live comedian who joked on the sketch show's Weekend Update segment, "She pays 60 grand for rent and all I have to do is stock the fridge."

But when their whirlwind engagement unraveled last October just as quickly as it came together, he was left searching for a new arrangement. 

"Does anybody have any open rooms?"
he cracked while co-hosting a benefit performance for the get-out-the-vote organization Swing Left in West Hollywood Oct. 20. "Looking for a roommate?"

In the end, there was just one taker with Amy Waters Davidson opening up the doors of her home on New York's Staten Island. As the comic put it, "I had to move back in with my mom." 

Not as though that's cramped his style. Nearly four months after his high-profile split that sparked the expected headlines and at least one hit song, the 25-year-old isn't just making the comedy club rounds, he's fully back in the relationship circuit with one source telling E! News he's "dating again." 

For the man once most famous for being SNL's youngest cast member, that doesn't just mean taking a swipe or two at Tinder. Rather, his bounce back game involves romancing one of Hollywood's most eligible bachelorettes. A University of Oxford-educated thespian, Kate Beckinsale has talent, a successful movie franchise, the type of looks that tend to earn her a reserved spot on most beautiful lists and, as evidenced by her Instagram feed, a sharp wit.

And, as of late, Davidson is the one she's choosing to share it with. "Kate thinks he's the sweetest and nicest guy," a source tells E! News. On paper, the twentysomething comedian, who spent two years with writer-producer Cazzie David, 24, before dating Grande, and the seasoned actress, mom to 20-year-old daughter Lily Sheen with actor ex Michael Sheen, "may seem like an unlikely match," admits the source. "But she thinks he's great and she just loves all the laughs she has with him."
