Ryan Seacrest was surrounded by millions of people in Times Square Friday night as he co-hosted Dick Clark’s New Year’s Rockin’ Eve. He took a break from American Idol to make the trip to the Big Apple while new AI judge Jennifer Lopez headed to Las Vegas with Marc Anthony. Last week Ryan laughed off rumors of an engagement to girlfriend Julianne Hough, though she was in attendance to lock lips at the stroke of midnight. Jenny McCarthy also got a surprise kiss from her new boyfriend, attorney Paul Krepelka. New Kids on the Block and Backstreet Boys shared the stage again performing a mashup of their greatest hits as they prep for a 2011 Summer tour that has most of you really excited. Willow Smith was in the spirit of the night whipping her hair back and forth while Ke$ha kept the party going with her chart topping hit "Tik Tok." Avril Lavigne debuted a new song, "What the Hell" and Jennifer Hudson showed off her fit frame while belting out the appropriately titled tune, "Feeling Good."
