At the premiere of The Lorax in L.A. Sunday, a condom accidentally fell out of Zac Efron's pocket on the red carpet. The actor, 24, quickly scooped up the gold packet and mouthed, "Oh, my god!" to his publicist.

The embarrassed star, who wore a Simon Spurr leather jacket, then covered his mouth to suppress his laughter while posing for photographers.

Efron later met up with Taylor Swift, Ed Helms, Danny DeVito and Rob Riggle, who also lend their voices to The Lorax.

Zac, who famously dated his High School Musical costar Vanessa Hudgens from 2007-2010, is currently courting Mirror, Mirror actress Lily Collins, 22. While on their recent visit to Ellen Degeneres, she suggests that he is dating his co-star Taylor, who was on the red carpet with Zac.
