Forget hooking up with his exes...looks like Nick Lachey may have found a new lady love!

We snapped the former boybander stepping out of Madame Royale last night with a mystery brunette, and we're not sure who she is, but from what we can see, she sure is a cutie!

I guess Nick's not interested in dating blondes anymore? Poor Jess...she probably thought she still had a shot!
