Who Is Kate Upton Kissing?

Kate Upton is one of the most eligible bachelorettes around right now … so, who was she just spotted kissing on the beach?!

A bikini-clad Upton, who just turned 21 on Monday, was photographed on Tuesday locking lips with Nikolaj Coster-Waldau, AKA, Jaime Lannister from "Game of Thrones."

But there isn't any real life funny business going on here. These two were just filming a scene in the Hamptons for their film "The Other Woman," which also stars Cameron Diaz and Leslie Mann.

However, the Sports Illustrated Swimsuit Issue cover model is hardly hurting for male company when the cameras aren't rolling. Upton was just photographed out to dinner with "Dancing With the Stars" pro Maksim Chmerkovskiy. The two dined alone to celebrate Upton's birthday in New York City at Scalinatella, a restaurant on the Upper East Side.

Us Weekly reported the duo were "very canoodly" and were even holding hands. "It was a very intimate meal," an eyewitness told the magazine. "They were set up through friends," another source added. "They just started dating."

Although a rep for Upton says the Vogue cover girl and Chmerkovskiy, 33, are just friends, a source also confirms to omg! that they were on a date.

However, the same source tells omg! not to read too much into it.

"She's single," an insider close to Upton tells omg!. "She has been going out with a few guys. She's having fun right now."

As she should be! The buxom blonde is quite the hot commodity.
