Miley Cyrus' recent extreme run-in with hair bleach and scissors has fans, fashionistas and most recently, Flavor Flav utterly confused. The two bumped into each other backstage at the iHeartRadio Festival in Las Vegas Friday night. With cameras rolling, Flav greeted her with an enthused "Gwen Stefani!!"

Whoops.

Sharing a laugh, Cyrus brushed off the mistake--and didn't bother to correct Flav, even after sharing a chat, a photo and a hug. She must be used to the comparison to the No Doubt singer and also P!nk, who has an even more identical haircut. It wasn't until they parted ways that someone informed Flav to his surprise that she was not Stefani, but Miley Cyrus! But Flav immediately went back to Cyrus to apologize, and all was well in the world.

If you had the sound turned off during Usher's 25-minute set at the iHeartRadio Music Festival in Las Vegas Friday, you might have assumed it was a tribute to the late Michael Jackson. Usher employed much of the King Of Pop's signature choreography as he dripped with sweat throughout his hits "OMG," "Yeah" and "DJ Got Us Falling In Love." But he was so good at it, it was refreshing, especially during the week of the release of the 25^th anniversary edition of Jackson's Bad album.

On Pink's new album, she's writing about volatile relationships, again—albeit mostly their upside this time. "I hate you, I really hate you —so much I think it must be true love," she sings, providing a tip-off that there's more loving than loathing on The Truth About Love, her sixth studio album.

PinkPink is having a very splashy mid-September, between the Tuesday release of Truth About Love and her weekend appearance at the iHeartRadio Music Festival. Although she's long been known as the gal who was ready to "get this party started," much of her songwriting over the years has been more lovelorn than celebrative. That's not so much the case with Truth, which suggests that Pink is experiencing enough domestic tranquility that she has a real reason to party now.

Pink has said that her previous album was written and recorded when she was an emotional mess, having been separated from Carey Hart. Now that they've been married for six years and have entered a more tranquil phase of their

When Miranda Lambert rolls into Las Vegas to play the iHeartRadio music festival, she'll definitely be all warmed up and ready to go. The country superstar has been busy on the road with her own solo headlining tour--and just jumped into touring this month with her other musical project, "Hell On Heels" girl-trio the Pistol Annies.

It's a good thing she's keeping her muscles warm, because the remainder of 2012 in general isn't slowing down one bit for Lambert. She's nominated for four trophies at the Country Music Association Awards in November, she's got a TV series in the works, she's working on new music for both herself and the Annies--and, of course, she's got to keep up with fellow celeb husband Blake Shelton's doings on the hit reality show The Voice. One definitely has to be the "Fastest Girl In Town" to keep up with all of that! However, Lambert managed a few minutes to catch up with Yahoo! Music about everything she's juggling at the moment.

LAMBERT: You know what, we're just going to do what we've been doing. We've been touring all year since January, we're winding down, and it was an amazing tour. So I think we're just going to bring what we've been doing! It's worked all year and it's been awesome. And I've got the Pistol Annies coming out, so that's a special extra little something that people get from us. I'll do my set and then have the girls come out and do two songs, and we're gonna do what we do and move on.
