Justin Timberlake Plays Volleyball In Cabo With Bachelor Party Pals

Jessica Biel doesn't need to be a worried bride-to-be during Justin Timberlake's bachelor party -- he's just working up a sweat on the volleyball court!

The 31-year-old engaged actor and singer enjoyed a rousing game of volleyball with his pals Sunday in Cabo San Lucas, Mexico. While some Timberlake's bachelor buddies took their shirts off to soak up the sun, the groom-to-be kept his on while playing in the grassy field. And in true bachelor party style, the boys did have coolers full of beverages ready on the sidelines.

Timberlake headed to Cabo on Friday after celebrating in Las Vegas Thursday. The Trouble With the Curve actor and his friends got their groove on to the sounds of DJ Spider at Tryst nightclub at the Wynn Las Vegas and enjoyed the outdoor pool venue of Surrender Nightclub at Encore. Although it was packed with models, Timberlake "was a good boy," an eyewitness told Us Weekly. "It was just him and the guys."

Biel, 30, and Timberlake have been dating for five years. As first revealed by Us, Timberlake proposed in Jackson, Wyoming in late December. The Total Recall actress told The Chicago Sun-Times in July that she wanted to enjoy being engaged and wasn't in a hurry to plan their wedding.

"Everyone tells me that being engaged is the really special moment," Biel said. "Not that it gets bad when you get married! But being engaged is just absolutely amazing. You're in this romantic, ahhhhh, breathless moment that I'm just trying to extend as long as possible."
