Ashlee Simpson partying too hard

OHMYGOSSIP — Ashlee Simpson‘s partying is starting to worry her ex-husband, Pete Wentz. The Fall Out Boy rocker is said to be concerned that Ashlee’s behavior will impact their young son Bronx.

Ashlee has been partying hard as she struggles to deal with her parents shocking split and news that her father Joe enjoyed a number of gay trysts.

“Ashlee is in the dog house right now with Pete,” a source tells RadarOnline.

“He’s concerned that she’s burning the candle at both ends and worried about the effect on Bronx if she continues in this current state.

“Pete’s told Ashlee that enough is enough, and she has to cut back on the partying. He’s even spoken to [her mom] Tina to get her take on the matter and make sure that he’s not overreacting in any way. She reassured him that he isn’t and said she’s been worried about Ashlee too.”

Ashlee displayed some “out of control” behavior at a Hollywood hotspot recently.

“She was downing drinks like there was no tomorrow,” a source said. “She asked for a straight shot and added it to her already mixed cocktail,” the source added.
