It's his first big TV series appearance since the WB's Twins. What? Not a fan? Okay, check that, it's his first big TV series appearance since Newlyweds! Better?

Reliable sources confirm that Nick Lachey is heading to the CW for at least one episode of the long-running fan-favorite series One Tree Hill later this season.

So who will he play? Which One Tree Hill lady will he be getting close to?

According to insiders, Nick will be playing a singer, former reality star and former boy bander who is dating Vanessa Minnillo. Yes, he is playing himself.

In the storyline, a record label wants to buy one of Haley James Scott's (Bethany Joy Galeotti) songs that she wrote for Nick Lachey's new album, but she is hesitant to sell her music.

He will then appear in person. Cheesiness and hearts fluttering will soon follow.
