Jessica Simpson has reportedly been asked to keep an eye on her younger sister Ashlee following reports that the single mom's alleged hard partying is out of control.
The 32-year-old "Fashion Star" mentor is currently well into her second pregnancy, and subsequently her mother Tina reportedly believes that she can help Ashlee curb her heavy drinking and hard partying.
"Tina's asked Jessica to look out for Ashlee and make sure she doesn't start partying too hard once again," a source close to the Simpson family allegedly told RadarOnline.com.
"With Jessica focusing on her second pregnancy, she's a calming influence on Ashlee because she doesn't want to go out on the town," the source went on.
In early March it was claimed that Ashlee, who has a history of concerning behavior, was so out of control that her ex-husband was considering getting temporary full custody of their 4-year-old son Bronx. Tina is said to be hopeful that Simpson will help keep Ashlee in check due to her more stable home life.
"Instead, [Jessica] prefers family nights in relaxing and has encouraged Ashlee to join them when they are all together, which she has been doing. Ashlee's been looking a lot more like her old self lately appears a lot healthier," the source revealed.
"However, Tina has told Jessica to keep an eye on the situation, just like she is, to see if Ashlee falls back into her bad old ways again only time will tell," the source went on.
Pete Wentz, 33, and Ashlee, 28, divorced in 2011 after three years of marriage and the singer was awarded sole physical custody of Bronx. The pair still shares joint legal custody though. Previous reports claimed Wentz grew tired of Ashlee's drinking, which prompted the divorce and it was recently claimed that he feared for the well being of Bronx.
"Pete is worried that Bronx's well-being could be affected if Ashlee continues to party hard, and he's concerned about her right now," a separate source said on March 3.
Ashlee is reportedly struggling to deal with her parents' ongoing divorce as well as rumors surrounding her father Joe's sexuality. Wentz, who has since moved on with model Meagan Camper, reached previously reached out to Tina regarding his growing concerns, according to a report.
"He spoke with Tina about his concerns and warned that if Ashlee doesn't get a grip and calm down the partying he won't hesitate to get a temporary full custody order in place for Bronx," a source said.
