Bruno Mars

It's never fun to get arrested. Well, probably -- we wouldn't know. But you would never guess that by these celebs' mugshots!

Just this past weekend 'SNL' announced that 'The Hunger Games' star Woody Harrelson would return to the stage on November 15, and so too do we know what A-lister will also make a return appearance the following week. 'Annie' star Cameron Diaz will make her own fourth appearance hosting on November 22, but what pair of musical guests can we expect to join her?

Bruno Mars is the kind of pop music artist who truly has fans of all ages, from kids who come into the city with their moms and dads on the train from Long Island for his concert, to a white-haired older woman who practically starts a dance party during intermission...

Warning: The following story and accompanying video are serious tearjerkers.

Excuse us while we pinch ourselves, because we still can't believe that this actually happened. Just in case you thought that Brad Pitt was only in New Orleans to bro out with Matthew McConaughey, he was actually there to host the Make It Right Gala, a charitable organization that helps to build homes to those in need. And in addition to his hosting responsibilities, he also shared some serious stage time with Bruno Mars for a cover of James Brown's 'Get Up (I Feel Like Being a) Sex Machine'.

There is more good news about the Justin Bieber and Austin Mahone collabo. It looks like this pairing is MUCH more than some loose, low-pressure fun in the studio. It seems like the real deal that will produce a song and they are working on an actual duet.

What better way to kick off the weekend than by watching this sweet baby wake up and rock out to some Bruno Mars?

A young singer by the name of Roomie, might not be a man of a thousand voices, but 14 is pretty darn good! Watch this short video as he mimics everybody from Bon Jovi to Bruno Mars and Adam Levine to even Rick Astley! ***There is a little NSFW language***

Bruno Mars, fresh off his most-watched Super Bowl performance, followed up with a visit to 'Ellen.'

Crooner Bruno Mars provided the halftime entertainment for Super Bowl XLVIII with an assist from the Red Hot Chili Peppers and a children's choir, the members of which held hands as they sang like cherubs for the first 30 seconds.

It's a special edition of Timeflies Tuesday -- just in time for Super Bowl Sunday!

The very last audition on tonight's 'American Idol' (Jan. 22) was Miley Cyrus look-alike Marrialle Sellars, who sang Bruno Mars' 'Grenade.'

Bruno Mars isn't simply gearing up for his performance at the Super Bowl halftime show. The singer will also launch the next leg of his Moonshine Jungle World Tour in spring 2014.

Bruno Mars is going to get hot in the freezing cold February Super Bowl -- and he's going to have some help. The singer personally enlisted the Red Hot Chili Peppers to join him for the halftime show!

The 2014 Grammy nominees for Best Pop Solo Performance come from a range of singers. Whether it's a former boy bander-turned-solo-success or a New Zealand newcomer, these artists represent the best pop music has to offer. Sara Bareilles, Lorde, Bruno Mars, Katy Perry and Justin Timberlake are all contenders for the honor. Who do you think should win the Grammy?

Oh Bruno Mars, you charmer. The crooner covered a Janet Jackson hit from the 1990s while performing in Las Vegas.
