Cheryl Cole is enjoying all Hollywood has to offer ... gorgeous weather and a dinner date with gorgeous dancer Derek Hough.

The twosome, who were reportedly dating earlier this year, dined together at Nobu in West Hollywood. Instead of walking out together, they chose to leave in separate cars. Sneaky!

Ms. Cole has been reportedly getting cozy once again with her ex-hubby Ashley. So what's with the former X Factor judge having a romantic dinner date with Derek? No doubt ... makes for a sexy love triangle.
