Justin Timberlake hit the red carpet to celebrate the release of The 20/20 Experience at LA's El Rey Theatre on Monday night. He was joined by newly single Ryan Seacrest, whose split from girlfriend Julianne Hough was announced last week. Ryan interviewed Justin during the event, which will be televised on Tuesday night on The CW, and their chat confirmed that Justin is in fact planning on dropping a second part to the album later this year. Also on hand for the bash was Emmy Rossum, Anna Kendrick, Nikki Reed, and a crowd full of fans, who were treated to a concert by Justin that included a performance of "Mirrors." He had made his way west after stopping over the weekend in Austin, TX, where he held a secret Myspace event.
