Ashlee Simpson and Pete WentzIt looks like Ashlee Simpson and Fall Out Boy’s Pete Wentz tried out all the, ahem, facilities at Pete’s new bar in New York.

According to onlookers at the opening night of Angels & Kings on Monday, the pair were inseparable all night, drinking scotch on the rocks together for the duration.

Sources told Star magazine: “They were completely absorbed with one another. Ashlee kept stroking Pete’s hair and whispering into his ear. They made a small effort to talk to their friends sitting at the table with them.”

At one point, “Pete whispered something into Ashlee’s ear. She smiled and they both got up and went into the bathroom together. They were in there for about 10 minutes.”

A second source told Us Weekly that the whiskey got to Ashlee in the end and Pete had to help her out of the club: “She was a little wobbly.”
