Zac Efron continues to overexpose himself with 'Entourage' cameo
MTV Movie Award winner and "High School Musical" heartthrob Zac Efron will be the latest actor to guest star on the Hollywood-friendly HBO comedy "Entourage."
E! News reported that Efron was filming at the Beverly Hills Niketown store on Tuesday, but nobody knows what, exactly, he'll be doing on the show.
Season Six of "Entourage" premieres on HBO on July 12 at 10:30 p.m. Other celebs signed on for cameos include Lil Wayne, Tom Brady, LeBron James and Aaron Sorkin, while Autumn Reeser and Kate Mara will guest star in more substantive roles.
Efron was most recently seen in the spring sleeper "17 Again," which took in more than $60 million at the domestic box office.
