Jessica Simpson isn't the only star to play around with a new hairstyle this weekend. While on tour with his band 30 Seconds to Mars, Jared Leto took a little break to get his hair done. While doing so, he kept his fans updated by tweeting the progress. After showing a photo of Manic Panic dyes, he posted a shot of him with a very Tank Girl bleached-and-shaved style. ("You're too f_____'in blonde," he wrote.) Before long, we got one more photo that showed off the final style: a bright pink mohawk with blond roots, proof that what happens in Vegas doesn't always stay in Vegas. Half of you don't love it when men color their hair, but if anyone can pull it off, it's a dude with a guitar. Think Jared does?
