Cele|bitchy | Nick Lachey and Petra Nemcova?

Nick Lachey was flirting with supermodel tsunami-survivor Petra Nemcova at the Kentucky Derby. He may not be over Jessica yet, but he seems to be enjoying the possibilities of moving on:

It’s an all-new couple alert as “Extra” breaks news about the latest beauty in the life of Nick Lachey. And the sexy temptress isn’t keeping this romance a secret!

Supermodel Petra Nemcova and the hottie singer were spotting getting super cozy over the weekend at the Barnstable Brown Bash at the Kentucky Derby.

The duo arrived solo on the red carpet. Sources told “Extra” it was Petra who approached Nick at the party and was very hands on.

That’s pretty vague, but maybe they were hanging out and flirting. Nick is a great guy while Petra seems really kind, so they would make a very good couple. It’s way too early to tell though.

Nick continues to be kind in his public quotes about Jessica, and doesn’t dismiss a reconciliation. It sounds like he is moving on, though.

“It was this feeling inside of me, you know, I don’t want to be this angry person. I don’t want to be bitter about this.” Nick adds “I don’t think I could say that I’ve completely let go. There’s real love there. There always will be. I can’t say what the future holds.” So will the couple get back togather? “I can honestly say with 100 percent sincerity that I want for us both to be happy and however that happens, that’s how it meant to be.”

Meanwhile, according to In Touch Nick Lachey has been keeping busy with a mysterious blonde while in Vegas last week.

Nick is quoted as saying “his girlie” is his work.

Here’s Nick on Total Request Live and Petra at 3rd Annual “Event to Prevent” Gala yesterday put on by the Candies Foundation. She is also shown on 5/4 at the grand opening of “The Collection” at Chevy Chase.
