Justin may be single again, but he surely wasn't dateless the other night at the premiere of Alpha Dog. He took his mom Lynn to the show. Then the two hit the after party together where JT met up with Scarlett Johansson. Justin and Scarlett then apparently danced and hung out until the club closed and JT took off with his mom. So maybe there is something more going on between these two besides shooting JT's latest video for What Goes Around Comes Around... Stay tuned. Hopefully they'll provide some excitement for us this weekend.
