Encore, Encore! The Year of Pop Group Revivals

Bubblegum pop fans can rejoice because 2012 is proving to be a year of band reunions. On Friday morning, 98 Degrees packed Rockefeller Plaza for their first televised appearance in years. Plus, The Jonas Brothers hit the radio airwaves to announce their rebirth. Beckoning N*SYNC and Destiny's Child for a reunion! You're next.

Three 98 Degrees members—Nick Lachey, Drew Lachey, and Jeff Timmons—never completely left the spotlight after taking an extended hiatus since 2002. Fourth crooner, Justin Jeffre, kept a bit more under the radar. Over the past decade, Nick has hosted numerous shows, including Live! With Kelly and The Sing-Off. Brother Drew is preparing to jive and salsa his way to a second mirror ball trophy on the Dancing With the Stars: All Stars season. The ab-tastic Jeff raised the temperature when he gave fans an eye-full during a stint with Chippendales last year. After hinting at a long-awaited reunion by re-launching the band's website, 98 Degrees performed together again on Today on August 17 and the following day at the MixTape Festival on August 18 in Hershey, PA.

Posh, Sporty, Scary, Ginger, and Baby Spice added flavor to the Closing Ceremonies of the Olympic Games on Sunday night. Even London's mayor Boris Johnson danced to Wannabe and Spice Up Your Life. No word yet on if this was a one-time gig or if they'll launch a full-fledged tour. The group previously reunited in 2008. A theater show, Viva Forever! The Musical, a new musical based on the songs of the Spice Girls, is slated to raise the curtain on November 27 in London.

Pop/Rock group No Doubt has reassembled to release their first album since 2001's Rock Steady. The first single off the record, Settle Down, has already hit airwaves. The cover art for Push and Shove was recently revealed on the band’s website, as was the track list of nine brand new songs. Gwen Stefani and crew hosted a fundraiser for Barack Obama on Sunday, with Michelle Obama in attendance. To the delight of fans, No Doubt proved they still have it in 'em recently on Good Morning America and the Teen Choice Awards. Their next scheduled appearance is at the iHeartRadio Music Festival on September 21 in Las Vegas.

The Backstreet Boys never completely dismantled, but original member Kevin Richardson took a leave of absence for several years. During that period, BSB joined forces with New Kids on the Block to form super-group NKOTBSB. On July 17, all five guys appeared on Good Morning America to announce "Backstreet's back, alright" and recording a new album in London. They'll return to the morning news show on August 31 as part of the program's concert series.
