As you can see, Baby Biebs isn’t exactly laying down tracks just yet -- more into crawling around and grabbing whatever he can while dad’s amused friends look on.

Ozzy Osbourne and Axl Rose met for the very first time in their lives over the weekend, and that's left fans shocked the two rock icons finally crossed paths.

Ozzy shared a backstage photo on Instagram on Monday, of himself and the Guns N’ Roses frontman shaking hands, writing ... "My first time meeting Axl Rose, at my age you don’t get to meet many legends, seriously an utter gentleman." The photo was from Saturday’s "Back to the Beginning" concert in Birmingham, England.

It's the 4th of July weekend -- and this star's shining brighter than a "Firework!"

This Santa Barbara-born singer was just another one of the "California Gurls" when she shot to superstardom in the late 2000s with a string of tracks that rocketed her into the stratosphere -- which she actually passed through on a Blue Origin flight with Lauren Sanchez!

And here's another hint ... she also had a long-term relationship with Orlando Bloom, but it looks like their romance is pushing "Daisies!"

Kelly Clarkson fans likely never imagined a moment like this -- the Grammy winner canceled the opening show for her Las Vegas residency just 90 minutes before it was supposed to start.

KC broke the news on Instagram Friday night and blamed the shocking cancellation on her voice ... saying she needed time to rest because the residency prep and rehearsal took a "toll" on it -- and she wants everything to be "perfect" for her dedicated fans.

She added ... "We have been working 24/7 to make Studio Sessions the most intimate and extraordinary experience with and for my incredible fans. I am beyond grateful that you always show up for me and I am devastated to have to postpone tonight and tomorrow’s opening at Caesars."

We've got a health update from Paul Simon -- the Simon & Garfunkel icon underwent a successful back surgery to alleviate "severe” back pain that forced him to cancel 2 shows last month.

The positive update was released on his official Instagram page Thursday ... though there is a caveat. His team says he needs more time to recover, so his July 7 concert in Long Beach, California is being postponed to the following day.

It seems fans don't have too much to worry about -- the statement says the decision was made out of an "abundance of caution" to ensure PS is ready to hit the stage "at the top of his ability."

Lizzo is boldy reminding haters that the 'Truth Hurts' ... 'cause she just stripped down to her underwear to show off her weight loss and detail exactly how she slimmed down.

Lily Allen isn't sugarcoating a thing -- boldly revealing she’s had "quite a few" abortions ... so many, she says, she can’t even remember how many.

Yup, the British singer laid it all out on the latest episode of her 'Miss Me?' podcast -- telling cohost Miquita Oliver that if she really thought about it, the number’s probably around four or five.

The reveal didn’t faze Miquita one bit -- she chimed in saying she’s had around five abortions herself, adding how freeing it felt to say it out loud without anyone there to judge or shoot them down for it.

Post Malone took a tumble off stage during a concert in Arizona — and the shocking moment was captured on video by a fan.

Nostalgia just slammed into Vegas ... 'cause when New Kids On The Block kicked off their Right Stuff residency, members of a rival boyband crashed the stage -- and the crowd lost it!

Catch the clip -- NKOTB were hyping up the crowd last weekend at the Park MGM, asking who wanted to marry them back in the '90s … and while fans screamed, Backstreet Boys’ Howie Dorough popped up with a cheeky banner that read, "I Do."

Howie later pulled up with AJ to crash the stage ... and it was nothing but boy band bromance -- hugs, laughs, and major 1990s nostalgia as they embraced NKOTB like long-lost brothers.

If you were expecting a boy band showdown -- think again. Even with BBs launching their Millennium Sphere residency later this month, both groups proved there’s more than enough room (and love) to go around on the Vegas Strip.

But with NKOTB already kicking things off with a bang, you can bet it’s lit a fire under the Backstreet Boys -- and sources tell us they’re grinding hard, rehearsing 12 hours a day, 5 to 6 days a week, to gear up for their massively anticipated Sphere takeover.
