Since chopping her hair last month, Ali Larter took a few more inches off of her shaggy layered bob last week. And now she wants to go even shorter! "I want to shave it up the back and I keep tempting my husband and saying 'Can I do it?'" she told at the launch of Irene Neuwirth’s new diamond jewelry collection in Los Angeles. "He is totally supporting it, so we may go to the next level." And that fits right into Larter's laid-back approach to switching up her 'do. "Change is great," she said. "I don't take it that seriously and I have fun with it." Good advice!
