New couple alert!

E! reality star Khloe Kardashian is dating Los Angeles Lakers forward Lamar Odom, has confirmed.

"They are a couple now!" a source tells Us. "So cute!"

Adds Khloe's sister Kim, "He's a great guy!"

On Thursday, Khloe, 25, and Lamar, 29, hit West Hollywood's Guys and Dolls, dancing and holding hands all night.

In their booth, "He was holding her hand and every time a good song came on, she would pull him up to dance and steal kisses here and there," a source tells Us. "There is no denying the chemistry between those two."

After dancing the night away, Khloe and Lamar — who just signed a four-year, $33 million contract with the Lakers (he helped them win the NBA Championship in June) — left the club hand in hand.
