Don't drink and dial!

Ashlee Simpson filed for divorce from Pete Wentz in February, but the 26-year-old singer-actress still has the 32-year-old bassist on her mind, at least when she's had a few!

A source tells the new Us Weekly that Jessica Simpson's kid sister recently placed an inebriated call to Wentz, with whom she has a 2-year-old son, Bronx. "Ashlee was telling Pete how much she misses him and wants him back," says the source; a rep for Simpson denies the call ever took place.

And although Simpson is dating Boardwalk Empire's Vincent Piazza, a friend of Wentz tells Us that Simpson is so desperate to win him back, she even asked his sister for help -- with no luck. "He will never go back to her," the pal says. "He's in a good place."
