Pete Wentz Thinks Pink, Denies Buying Blue

The dad-to-be performs at the Santa Monica pier while Ashlee watches backstage

Is papa-to-be Pete Wentz thinking pink?

Probably, since his band performed at the Victoria's Secret Pinkapalooza event yesterday at the Santa Monica Pier.

And despite the rumors, Pete swears he and Ashlee never bought blue baby clothes at Petit Tresor.

"I've never shopped there!" he told E! News. "Tom Cruise sued a baby store for saying they shopped there, and I'm broke."

While he didn't disclose the sex of the baby, he did admit he feels "very responsible" now that Ashlee's expecting. And yes, he's reading the baby books, along with soliciting advice from current dads. 

Ash was also in the house yesterday, but she skipped the carousel ride.

Instead, the preggers pop star (who canceled her own summer tour) hung backstage and watched her man perform to a packed house.
