At the second annual Rebels With a Cause gala on Thursday in LA, there were plenty of amazing groups getting rebellious together. Isla Fisher  and her husband, Sacha Baron Cohen , had fun with Jonah Hill ; Pharrell Williams's wife was mildly overshadowed by his newest hat; and Chris Pine made his first postarrest appearance  with friend Anna Kendrick . However, the most exciting duo was John Stamos and Bob Saget, who had another laughter-filled Full House reunion . Elsewhere in the TV realm, January Jones showed off a bold and sweet look  that is the complete opposite of her TV persona Betty Draper's style. Though, with the premiere of Mad Men's final season  less than a month away, we'll be seeing her in '60s mode again in no time.
