Don't Miss:

Olivia Munn joined the bob club in December, and we caught up with the actress at our Summer Soiree to talk about her shorter ‘do! “I cut it for I Don’t Know How She Does It. It was my idea,” she said. “They were so excited because actresses usually fight about cutting their hair, which I get, but I felt like it was something the character would have. It’s very easy and effortless.” The best thing about having a bob? Sleeping in late! “It takes the most minimal amount of time to get ready now,” Munn told us. “I haven’t has it this short since I was 12. I really like it!” Munn is going even shorter for Aaron Sorkin’s new HBO pilot, in which she plays a financial analyst. Tell us, are you planning on shortening your ‘do this season? Let us know in the comments!
