Actresses Jaime Pressly and Estella Warren got into a confrontation at a Hollywood club after Warren walked off with an iPhone belonging to Pressly’s assistant. The two were at a party Saturday where the assistant realized her handbag was gone. Warren had also been at the bash, and when Pressly and her aide activated the “find my phone” app, the device was tracked to club Bootsy Bellows, where, “They found Estella holding it,” a spy said. Jaime grabbed Estella’s bag and found her assistant’s keys and wallet. But Warren’s rep said she picked up the bag by mistake and was shocked by Pressly’s “aggressive” behavior. Cops were called but both sides declined to press charges.
