Seems like things are getting more serious between the socialite and her NFL football playin’ beau!

Though the new couple was out with four other guys at New York’s SL nightclub over the weekend, they only had eyes for each other.

A source said:

They shared many cute kisses and they seem to be in the honeymoon phase.

Guess it’s true when people say you never know when you’re going to meet someone. Back in June, an insider revealed how they started hanging out:

They met at a restaurant in Los Angeles a few months ago and exchanged numbers and have been talking ever since. They’ve had a few dates and it’s going really well.

Kardashian even introduced him to her family already! Gotta get in good from the beginning with that group :)
