Reportedly, an intoxicated Ashlee placed the call to Wentz, the father of her 2-year-old son Bronx, and repeatedly told him "how much she misses him and wants him back."
They say honesty is the best policy, but according to the report, Ashlee may have gone a little too far, considering her "extremely inebriated" state.
Ashlee filed for divorce from Pete back in February of this year, citing "irreconcilable differences," and since the announcement of their split, Ashlee has been romantically linked to Craig Owens, one of Wentz's rocker friends and 'Boardwalk Empire' star, Vincent Piazza.
As for Pete, he is rumored to have reunited with his pre-Ashlee ex, actress Michelle Trachtenberg.
