Swoon!

Zac Efron headed to a business meeting in Beverly Hills before grabbing lunch at The Palm today, and the actor showed off his muscles in a t-shirt with Tupac on the front. Gangsta! His guns have gotten so big that they make his legs look tiny in those skinny jeans.

The Hollywood heartthrob came out to support his pal Seth Rogen at the premiere of The Interview last night, so let's hope that the Sony hackers don't go after him next! We doubt the High School Musical star wants his dirty laundry aired. We all remember when he claimed he was looking for late night "sushi" on Skid Row and got into a fight with a homeless man!
