After hoisting High School Musical co-star Ashley Tisdale atop his shoulders the day before, Zac Efron showed off his American guns at a 4th of July party in Malibu.  Efron cracked open a cold one while partying with Brody Jenner beachside.

After the photos of Tisdale and Efron surfaced, the Hellcats star took to her Twitter page to clear up any rumors about a fling, according to TooFab.com: “Don’t believe all pictures. People r gonna come up with stuff to say bc it sells! I had such a great birthday party with my friends, Family, and BOYFRIEND Scott. I will not let stupid rumors ruin all the fun we had! Xoxo.”
