So you think you know your 'tween pop lore -- your teens have memorized every line of dialogue from "Twilight: New Moon" and never miss an episode of "Glee." But OMG, Robert Pattinson and Taylor Lautner are, like, so last year! Prepare to be updated as we introduce the newest batch of up and coming hunks (your kids will think you are super cool!)
Justin Bieber -- Get used to seeing a lot of Justin Bieber! Discovered on YouTube singing versions of songs by Chris Brown, Justin Timberlake and Usher (who's now his mentor), the toothy, 16-year-old Canadian just scored the No. 1 pop album (My World 2.0) in the country and claimed the cover of People magazine. Next? "Saturday Night Live." Duhhh!
The Jonas Brothers -- Nick, Kevin and Joe are still the reigning king heartthrobs of teendom, after debuting on an episode of the Disney Channel's unstoppable "Hannah Montana" franchise. Besides being nominated for a Grammy (Best New Artist) and posing for the cover of Rolling Stone, they've gone on to break the hearts of quite a few pop princesses (Taylor Swift and Miley Cyrus, to name a couple). Nick is now touring solo, however, with his new band Nick and the Administration.
Robbie Amell -- This blue-eyed hottie made a splash in the big-screen comedy "Cheaper by the Dozen 2" and as cute killer bait in the thriller "Left for Dead." But you can catch him regularly on Nickelodeon as the love interest of "True Jackson, VP's" Keke Palmer.
Kendall Schmidt -- This likeable blonde boy-bander plays prankster Kendall in "Big Time Rush," Nickelodeon's new series about four hockey pals from Minnesota who get recruited to form a singing group. Kendall plays BTR's lead singer. In real life, he got his start as one of Haley Joel Osment's stand-ins for the movie "A.I.: Artificial Intelligence."
Paul Wesley -- Watch out, Robert Pattinson! There's a new Count Hottie in town. Paul Wesley plays reluctant teen bloodsucker Stefan Salvatore in The CW's "The Vampire Diaries," a role that frequently requires him to doff his shirt. He got his start in soaps like "Another World," and recently guest-starred on "24" and "Everwood."
