1. JONAS BROTHERS

Disney Channel stars Kevin, Joe and Nick need no introduction after their hit movie ‘Camp Rock.’ In August, the teen pop sensations released their third studio album ‘A Little Bit Longer’ and then hit the road on tour to promote it. Though they have been known to break a few hearts, the brothers all wear purity rings and vow to save their virginity until marriage.

2. David Cook
It’s been quite a year for David Cook. This reality show alum went from ‘American Idol’ to record-breaking rock star almost over night. After winning the seventh season of the show, Cook debuted eleven songs on the Billboard Top 100 in one week, shattering the previous record set by Miley Cyrus in 2006.

3. Chris Brown
As if his platinum CD ‘Exclusive’ wasn’t a big enough hit, Chris Brown released a deluxe version of it called ‘The Forever Edition’ in 2008. The re-release featured a DVD of his concert tour and four new tracks, including the hit ‘Forever.’ Chris Breezy also collaborated on other hits such as ‘No Air’ with Jordin Sparks.

4. Mariah Carey
Mariah’s star shined brighter than ever in 2008. Her single ‘Touch My Body’ became her 18th number one song, making her runner-up for the most number ones ever. In April, she shocked everyone by marrying Nick Cannon after dating for only a few weeks. She also proved her acting chops with a cameo in the film ‘You Don’t Mess with the Zohan.’

5. Lil Wayne
This year was full of ups and downs for the self-described “best rapper alive.” In January, he was arrested for drug possession and a slew of other charges. His record ‘Tha Carter III,’ released in June, went double-platinum and his single ‘Lollipop’ topped the charts. On October 22, Lil Wayne welcomed his son into the world.
