Jessica Biel and Justin Timberlake go solo…again but still together?

The groundswell of chatter regarding the shaky connection between Justin Timberlake and Jessica Biel has become so relentless, Justin’s mom has now stepped in to restore some hope of calm.

Justin was seen partying hard – and alone – in Las Vegas this weekend, but Timber-Momma, Lynn Harless, says he’s not up for grabs. “He’s found someone that’ll golf with him, give him a hard time when he deserves it and stand up to him,” the lady told E.

Justin, 28, was in Vegas to act as host for a celebrity golf tournament and a benefit concert to raise funds for the Shriners Hospitals for Children. On hand to help were folks like Alicia Keys, Taylor Swift, Snoop Dogg, TLC, Ciara and Jay Sean.

But once the good deeds got done, JT hit the town – and Jessie was nowhere in sight.
