On Wednesday evening, James Corden had Gwen Stefani keep him company on his car ride to work, which was fun because they jammed out to some classic No Doubt and discussed how Gwen Stefani doesn't age (her secret is ~love~). Corden was very stressed about getting to work, so for a (fake) reason he asked some friends to help him out. Well, George Clooney is his friend. Julia Roberts isn't.
