Bruno Mars

If you've never heard of the English music producer, Mark Ronson before, I guarantee you won't forget him now. His old school, funk-inspired hit 'Uptown Funk' which features Bruno Mars is all over the place!

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

We’re highlighting two of the most touching videos that we’ve seen recently of celebrities interacting with fans. Take a look and then decide: Who has the sweeter fan video, Justin Bieber or Bruno Mars?

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?

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.'
