Demi Lovato is a hair chameleon, and she changed colors yet again! The starlet, who never lets any one shade get stagnant, went from bright blond to bright blue, debuting her new look (as well as her new single) on 'The Tonight Show.'

Get your bags packed! You could be headed to the Cayman Islands with Train!

Amid all the other major premieres this week and next, we'd nearly forgotten that 'SNL' will kick off its 39th season this coming Saturday, with alumni Tina Fey taking up hosting duties and Arcade Fire on the musical side. The first preview for Fey's return to the 'SNL' stage has arrived, but has everything already come unhooked?

By her own admission, pop diva and the ultimate queen bee Cher is not a morning person. That's why today (Sept. 23) marked her first time performing on a morning TV show...ever! She dutifully got up early and hit the stage in Rockefeller Center on a brisk autumn morning to entertain the NYC faithful.

Move over, Jimmy Fallon: You're not the only NBC television personality having a public bromance with Justin Timberlake -- and Matt Lauer is trying to one-up you by making it official!

Beautiful. Just beautiful. That's how Demi Lovato and Naya Rivera sound on their lushly harmonized duet of 'Here Comes the Sun' from the Beatles' 'Abbey Road.' The duo sang the song for an upcoming episode of 'Glee.'

Miley Cyrus and Katy Perry will help make Saturday nights even more exciting very soon. Both artists are among those set to appear on 'Saturday Night Live' this season, NBC confirmed today (Sept. 9).

Just when you thought 'SNL' couldn't have put that Lindsay Lohan rumor to bed any harder, the first three episodes of the 2013-14 season will blow the lid off '30 Rock' altogether. Alumni Tina Fey will host the September 28 'SNL' premiere, with the weeks that follow to include the likes of twerqueen Miley Cyrus, Bruce Willis, and even a returning Katy Perry!

They'll be reunited! The original vocal coaches for NBC's 'The Voice' are returning for season 5 this month and they're all featured in a new promo for the show's return harmonizing together on the 1978 classic 'Reunited'.

Lady Gaga has both performed and appeared in a couple of sketches on Saturday Night Live and now the rumor is the next season will feature her following the footsteps of Justin Timberlake by performing both duties, hosting and performing.

Forget all about that crap rumor of Lindsay Lohan hosting the 'SNL' season 39 premiere, much more credible intel points to an even crazier female figure: Lady Gaga! Unsurprising given her showy VMA performance and upcoming album release, the queen of weird will return to the 'SNL' stage in season 39 to perform, but is there any chance the star will take up hosting duties as well?

If anyone even bothered to boo the performance of One Direction on last night's (Aug. 28) 'America's Got Talent,' thousands of delirious Directioners made absolutely sure no one would ever hear them.
