Taylor Lautner celebrates his 21st birthday with pals like Kristen Stewart

Twilight star Taylor Lautner celebrated his 21st birthday by gathering with friends, including former costar Kristen Stewart, at Lucky Strike Lanes in Hollywood on Feb. 11.

An insider told E! that when she arrived, "he got super excited and gave her a big hug. It was more of a best friend moment."

Robert Pattinson was not present at the bash, likely because he is shooting his latest flick The Rover in Australia.

Other attendees at the party included Ashley Benson and Patrick Schwarzenegger, according to Us Weekly, who spent the evening taking advantage of the private lanes and enjoying foods like pizza and chips.

Though Lautner has now reached the legal age to drink, a source told E! that the actor was only seen with soda.

Despite the excitement during the celebration, Lautner reportedly tried to make the bash as low key as possible.

“He didn't want people to sing 'Happy Birthday' to him, but his friends wanted to do it anyway,” the source said to E!.

The party ended at 1:30 a.m., but not without Lautner signing one of the bowling alley’s pins before its conclusion.
