Yum! Zac Efron & Vanessa Hudgens Get Hot and Wet

Zac Efron hasn't lost his beard.

The grizzly-faced Hawaii-loving hottie was spotted on a little vacation this week in Maui with girlfriend Vanessa Hudgens.

Just how wild did the scruffy one and his Rent gal get during their island getaway? Read on to find out...

Not wild at all—at least not in public.

The two enjoyed some beach time, surfing and lazying around in the sand. Vanessa sported a bikini that showed off her sexy bod while Zac's wet suit shirt hugged his muscled physique oh-so-nicely.

And we're happy to report that the two are as nice to fans as they are to gaze upon. While waiting at the airport for their flight back to Los Angeles, the two signed autographs and took pictures with a few fans.

However, they were pretty much left alone. Efron was wearing khaki shorts, a black T-shirt and Ray-Ban sunglasses. Ms. Hudgens was just as casual in yoga pants, a tank top and a white trucker hat. Once on the plane, they settled into their seats in first class.

The ultra-private couple kept the PDA to a minimum. "They were so nice and normal and down to earth," an eyewitness says. "And they were very very sweet with each other."

In other famous-couple vacation news, Beyoncé and Jay-Z continued their holiday in St. Tropez with lunch the other day at Club 55. And they weren't alone. Stars were crowding the Riviera hotspot at the time, including Elton John and his husband David Furnish as well as legendary fashion designer Valentino.
