New Couple Alert: Khloe Kardashian and Lamar Odom

Seems love is in the air for reality star Khloe Kardashian and L.A. Laker Lamar Odom — sources tell OK! the twosome, who stepped out together last night -- are definitely an item!

Khloe and Lamar hit up Hollywood hotspot Guys & Dolls Thursday night, and spent the night dancing and holding hands.

"They never left 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 witness tells OK!. "There is no denying the chemistry between those two."

After dancing the night away, the two left together hand in hand.

Sounds like the start of something good!
