What started out as a fun night ended with an ugly morning for two actresses in Hollywood. On Friday, April 5, Jaime Pressly and Estella Warren joined several other stars at a birthday party in L.A. Everyone was having a great time -- until Pressly's assistant's phone went missing, leading to a confrontation with Warren, 42, at Hollywood hotspot Bootsy Bellows. Things never got violent, but the police had to be called to intervene, and even then, it took hours to resolve the situation.
UPDATE: An insider tells Us that Pressly, 35, only intervened to help out her assistant, and that there was no cat fight. The actress simply wanted to get her assistant's phone back.
A source tells Us Weekly that Pressly and her assistant discovered that the assistant's purse and phone had gone missing at the original party location, a house in L.A. Using one of those "find my phone" apps, the pair reportedly tracked the phone to Bootsy Bellows, where Warren and several other party guests (including Zac Efron and Adam Lambert) were continuing the celebration.
According to the source, Warren claimed the phone was hers. "Jaime was trying to get it back," the insider tells Us. "She wasn't agressive, but she was forceful."
Warren maintained that she was the rightful owner, and Pressly insisted that the phone belonged to her assistant. At one point, the insider says, drugs were discovered in Warren's purse, which led to the police getting involved. "Jaime and her assistant were volunteering for a drug test. They said the drugs weren't theirs," the eyewitness tells Us. "It was this crazy mess."
The West Hollywood Sheriff's Department says that they responded to two calls at Bootsy Bellows on April 5 -- a theft, at around 2 a.m., and a stolen vehicle -- but no other details were immediately available, as the investigation is still active.
