Do you hear what we're hearing? It's the distinct sound of the pot calling the kettle black. Miley Cyrus is pleading with Justin Bieber to cool it now that he's a worldwide superstar.

Seriously though, Ariana Grande could sing the phonebook and we would listen. Her amazing vocal chops are showcased on the stellar new track 'Almost Is Never Enough,' which also features Nathan Sykes of the Wanted.

Even though Mike WiLL Made It previously said that the line on 'We Can't Stop' says, "dancing with Miley," Cyrus is claiming otherwise. Maybe to boost her "street cred" points. We don't really know.

Selena Gomez literally just turned 21 and she is already partying like an old pro! The 'Come & Get It' songstress was first spotted at Julianne Hough's '20s-themed, 25th birthday bash on Saturday night with actress Lily Collins. Then, Gomez and Collins headed to the Roosevelt Hotel for her own birthday festivities!

What was supposed to be a three-hour tour (presumably) turned into quite the nightmare for Kelly Rowland and a group of friends, who chartered a boat to take them on a whale watching tour off the coast of Cape Cod in Massachusetts.

Happy birthday to Selena Gomez! The 'Come & Get It' songstress turns 21 years old today, and she's celebrating the only way a pop star knows how... by releasing a wild party video for her track 'Birthday.'

Man, can any pop stars make a video without it leaking early? Oh well! Selena Gomez's new clip for 'Slow Down' is seriously sexy.

At this point, if you're planning on going to a Rihanna concert, you know you have an hour window after the designated start time to get there.

Jay Z has accomplished a lot with his career. He's on track to beat the Beatles record for most No.1 albums, but maybe he thought there was something slowing down his progress. That dang hyphen! It's messin' with Hov's flow! So that's why Jay Z is dropping that pesky punctuation from his name.

Demi Lovato makes her directorial debut with her new 'Made in the USA' clip. Kudos to the pop star for giving her Lovatics something seriously amazing!
