Justin's New Girlfriend?

Rumors have been swirling for several weeks now that Justin Timberlake has split from Cameron Diaz. I remained skeptical until I heard that JT took none other than his mother to the premiere of his movie, Alpha Dog. Neither camp is fessing up to the split, but JT has been getting all kinds of close to Scarlett Johansson (who split from Josh Hartnett in November) lately. She's starring in his new video and allegedly snuck into the Alpha Dog after-party to be with her man.

If the rumors are for real, do you think she'll be a better match for Justin than Cameron? Weigh in with our newest iVote Hollywood poll.
