Buzzed Up Zac Efron's Undercover Exit

Having no luck in going unnoticed, Zac Efron tried to keep a low profile upon leaving Vanessa Hudgens' pad in Los Angeles, CA on Wednesday (January 5).

Showing off his buzz cut and looking buff, the "Charlie St Cloud" stud headed off to run errands while continuing to pad speculation of a rekindled romance with his former girlfriend.

Meanwhile, Zac will be upon the many stars descending upon the Nokia Theatre for the 2011 People's Choice Awards later in the evening.

The 23-year-old joins what will be a who's who of Hollywood, as Robert Pattinson, Kristen Stewart, Taylor Lautner, Taylor Swift and Katy Perry are all among the slate of expected guests.
