What an unlikely pairing!

Pete Davidson and Kate Beckinsale confirmed their romance is going full speed ahead over the weekend, and they weren't shy with their PDA, either!

The British beauty joined her new boo at his SNL after party, and they arrived and left the bash hand-in-hand. Then, the two took in a hockey game in NYC, and were photographed making out in the stands. We guess they have no problem letting the world know they're into each other!

"Kate is so into Pete and has been telling all her friends about him. They have great chemistry, and she loves hanging out with him whenever they get the chance to. She has such a fun, young, loving personality and is happy with him," a source dished to Us Weekly.

Still, they're dealing with a Ben Affleck and Lindsay Shookus type situation, as their home bases are on opposite sides of the country.

"Pete only has eyes for Kate. She’s cool and fun. It’s long-distance, but they’re taking it slow. She makes him laugh. He thinks she’s great and really smart. They have an incredible physical connection. Pete’s] thing with Kate is fun. He thinks she’s cool. They’re on opposite coasts though, so don’t count on it getting too serious," the source added.

Who knew he was such a ladies man?!
