While the verdict as to whether or not Justin Timberlake and Cameron Diaz have officially split is still out, speculation supporting the breakup is generating even faster now that Justin decided to take his mom to the premiere of his new movie "Alpha Dog" instead of Cameron. Although many reports state that Diaz and Timberlake have parted ways, there has been no confirmation from either publicist that the rumors are in fact true. Regardless, the Hollywood couple has not been seen together for weeks now.

Justin and his mom, Lynn Harless, attended the after-party following the premiere of the movie, where Justin 'flirted' with girls, got his picture taken. While this is nothing out of the ordinary for the "My Love" singer, what has got people talking is his encounter with super hot actress, Scarlett Johansson at a Hollywood club later that night.

According to Teen People, Timberlake and Johansson reportedly had an hour long conversation with the "Black Dahlia" star at a club called "Social" in Hollywood. After Justin and his mom hit the dance floor for a while, Lynn and Scarlett chatted until the club closed at 2 o'clock am. 

Although Justin and Scarlett spent quite a bit of alone time together that night, the rumors remain rumors. There were no signs of an actual romance as of yet, however, the two stars seemed very close and very happy with each other's company. Wonder what Cameron is thinking?
