It was an interesting night at the CMT Awards. Jason Aldean showed up with the woman who ended his marriage. Back in September 2012, Jason was caught on camera making out with former American Idol contestant, Brittany Kerr. Seven months later, his wife of 12 years filed for divorce. And now Jason’s mistress is strutting her stuff next to him on the red carpet. Host Kristen Bell showed a lot of spunk and tried to show her naughty side. Among the big winners last night, Miranda Lambert’s “Automatic” won a Buckle Award for female video of the year. That’s the fifth year in a row she’s won that. But Carrie Underwood beat her out for the top prize — video of the year for “See You Again.” The Band Perry won group video of the year for “Done.” And it was kinda fun to see Lionel Richie up there with Luke Bryan winning performance of the year for their CMT Crossroads version of “All Night Long.” Luke was pretty much speechless standing next to Lionel, saying, “I won an award with Lionel Richie. That’s all I gotta say.”

You may still be mourning the loss of “Bachelor Pad,” but ABC is coming back with something they call “Bachelor in Paradise.” How’s it going to be different? I don’t know, really, because I didn’t watch “BP.” But this go ’round, the contestants all travel to Mexico and live together for seven weeks in an “isolated romantic paradise.” And for seven episodes, we’re promised “new twists, shocking surprises, unexpected guests, and some of the most unlikely relationships in Bachelor history.” It premieres Monday, August 4.

Rob Kardashian reportedly is so upset with his mom that he’s considering lashing out with a tell-all book. “Star” magazine is reporting that Kris Jenner treats Rob like dirt. She picks on him for his weight and his failed sock line, and he says she’s a “monster.” Reportedly, Rob is considering writing a book revealing all the family’s secrets. It’s believed he could get up to $20 million for it.

Adam Levine is actually going through with it! He’s marrying Behati Prinsloo at the Hotel El Ganzo in Los Cabos on July 19. It will be a 3-day affair. The rehearsal dinner on Friday night…the wedding and reception on Saturday…and a big farewell party for the wedding guests before Adam and Behati take off on their honeymoon.

Sources say to get ready — there could be another 15-20 minutes of Justin Bieber footage coming our way. Will it be more shocking than what we’ve already seen? A source told TMZ that this footage — which was recorded when Justin was 14 or 15 years old — is all from the same guy who’s been trying to blackmail Justin for years. But, the source says, Justin knew at the time what he did was wrong and that he went to Usher and Will Smith, who helped educate him. Justin’s manager Scooter Braun posted last night, “Some mistakes have no excuses. They are just wrong. But how a man reacts to those mistakes . . . defines him more than the mistake itself.” And it looks like Lil Wayne, Birdman and the rest of Young Money Entertainment have Justin’s back. Young Money president Mack Maine told TMZ that everyone on the label has worked with Justin and there’s not been a hint of racism on his part. He said Justin “doesn’t have a slave mentality. He treats his people with respect.” On top of that, Mack confessed to making racist jokes as a kid that were just as offensive as the ones Justin told, only he didn’t get caught.
