How was he not melting?

Johnny Depp arrived to give a rooftop performance with his band Hollywood Vampires on Jimmy Kimmel Live! yesterday, and the actor was clad in wool pants, a vest, and a fedora even though temperatures in L.A. were over 100 degrees! In fact, it was allegedly the hottest day of the whole year!

The actor formed his musical group with legends Joe Perry, Alice Cooper, Matt Sorum, and Duff McKagan, and it sounds like the Pirates star can hang with the big boys even though he's relatively new to the music industry. Alice Cooper revealed how they all came together to Rolling Stone Australia.

"He comes in and he plays with us, and he knows everything...No matter what people yelled out, he knew it. 'Brown Sugar?' 'Yeah, yeah.' We realized this guy could play," he explained. "We started saying, 'Let's do an album.' I'd never done a covers record so I said, 'I'd like to do one in honor of all our dead drunk friends, the guys that we used to drink with that are now gone," he added.

On a totally unrelated note, what is happening to the former Hollywood heartthrob's looks?!
