Lollapalooza turned into Muddypalooza this weekend ... with festivalgoers trading the mosh pit for a mud pit.

The scene at Chicago's Grant Park looked less like a music festival and more like WrestleMania in a pigpen ... as fans squared up in ankle-deep sludge and threw down for a roaring crowd.

Two shirtless dudes kicked off the filthy fight card ... grappling and rolling through the muck before a pair of women turned another patch of Grant Park into their own muddy main event during The Neighbourhood's set.

Time to spread that sisterly love, and what better way to do it than with some of the most famous celeb sisters ... some of whom you may be shocked to learn have a sibling at all!

Sunday is National Sisters Day ... and, of course, you've seen the glorious Bailey pair and the iconic Olsen twins ... but have you ever seen Dua Lipa's younger sister, Rina! You'll thank us later ... the Lipa genetics gave us not just one, but two sexy bombshells!

Speaking of bombshells ... no group of sisters has given us more jaw-dropping spectacles than the Kardashian and Jenner sisters.

It should be illegal to look this good at 34 ... but Charli XCX knows we love it when she's rocking out in barely-there thongs and thick shades.

That's right ... It's Charli's 34th birthday, and there is a whole lot we "Fancy" about this British beauty.

Like this sexy snap of Charli sipping a cocktail in the sun ... in a tiny black bikini, of course.

Don't drool too much in the kitchen ... although we get it, Charli's looking too damn good in an almost see-through shirt, leaving pretty much nothing to the imagination.

That's okay, Charli, we'll leave the imagination to you ... and we're happy to just admire.

The need for speed is hittin' hard amongst the celebs, and they're taking it full throttle on jet skis!

Are Stella Hudgens' looks over the years catching your eye?!

Here is a 22-year-old version of the actress at a Refinery29 party in Los Angeles back in 2017 (left).

And, nearly a decade later, Sexy Stella has been turning heads all summer with her voluptuous looks on full display (right)

We know that she's the younger sister of Vanessa, but the question here is:

Good Genes or Good Docs?!

The mystery of Nolan Wells' death has only deepened, and Tony Romo could be out of a job. So we gotta ask ...

Keke Palmer put up this red-hot lewk earlier this week in the Big Apple -- and while you can't touch her vibe, we made some sneaky touches of our own 😜 Can you track down the minor changes?!

The hot mama fanned herself while striking a comedic face.

It's gettin' hot in here, so the stars are hangin' out on the terrace! Models Kara Del Toro and Abigail Ratchford are quite the babes on balconies, donning sexy outfits and flaunting their bods.

So, who are you joining on the deck?!

The question here is: Who'd You Rather?!

A jet ski operator is lucky to be alive after he slammed into a dock at full throttle ... and it seems a particularly difficult stunt caused all of the problems.

Dillan Stapler -- a jet ski influencer who is part of the "Lanier Crew," a group of jet skiers based out of Georgia -- shared a video of himself running straight into a dock.

Check it out ... he crashed at full speed and is jettisoned off the jet ski -- landing in a heap on the unforgiving wood.

Ray J says he'd gladly get back together with Princess Love ... but the conditions have to be right ... and it's not going to be easy ... or cheap.

Ray stopped by "The TMZ Podcast" and Towanda asked him if he could ever see the day where he's back with estranged wife.

While he says he would "love" to work things out with Princess, they need to make some adjustments ... and they need time and a lot of money.

Iconic blonde bombshell Donna Mills is joining OnlyFans at 85 ... and she's confident the risqué is worth the reward.

The film and TV star tells TMZ ... her fans have been loyal and supportive through the years ... and now she's going to share a little something back with them.

We don't know just how naughty the "Knots Landing" star intends to be ... but she says the direct connection will allow for some "quality time" with fans ... and give them a glimpse of who she is.

This drop-dead gorgeous actress knows exactly what she's doing with her melons on full display ... and we're taking another trip to the farmers market!

The starlet has become a household name thanks to her starring role in a hugely popular HBO series ... but she's also a savvy businesswoman -- and knows how to peddle her goods.

This week's Cheek of the Week is anything but meek -- Think you know who she is?!

She's got a couple songs written about her -- notoriously from her hot hubby, and when he's not dropping jaws on the beach or hittin' the Rhode, catch her hangin' with Baby Jack!

Her cheeks are "Everything Hallelujah!"
