Taylor Lautner, Twilight’s werewolf heartthrob, celebrated his 21st birthday with a bowling bash at Hollywood’s Lucky Strike Lanes on Saturday.

The down-to-earth actor, although turning the legal drinking age, went without booze at his party. Instead, he stuck with soda and munched on pizza, sliders and cupcakes. Not wanting to draw attention to himself, Lautner asked his friends to not even sing him “Happy Birthday,” and kept it casual in a backwards baseball cap and zip-up.

Making an appearance at the bowling alley was Lautner’s Twilight costar Kristen Stewart, 22. "When Kristen Stewart arrived," a source told E! News. "He got super excited and gave her a big hug. It was more of a best friend moment." Pretty Little Liar's Ashley Benson, 23, was also reportedly in attendance.

Lautner can be seen later this year in Grown Ups 2 as frat boy Andy alongside Adam Sandler and Kevin James.
