Beauty

We now know why Chris Brown kept the silky panties some chick handed him​ while performing on stage Saturday -- the chick is SUPER HOT, and her panties came unused ... but sweaty.

TMZ has learned the undies tosser is 21-year-old Carol Quiroz -- and she tells us she's such a HUGE CB fan ... she had to make her presence known at the Anaheim show Saturday night.

Carol says her plan was simple ... "I wrote my name, number and Instagram on the thong in permanent marker. I got his attention and handed it to him."

Groupie 101.

Carol also cleared up the most important detail -- the panties were NOT used, but she admits she was holding on to them in her bra. "I definitely had boob sweat on the panties."

For the record ... Carol says Chris hasn't contacted her. Yet.

There are many benefits to going to the gym, but being able to brag about it on your respected social media outlets tops the list!

Samuel L. Jackson's looks are off the chains.

Here's the foul-mouthed 47-year-old "Pulp Fiction" gangster hanging out in Beverly Hills back in 1995 (left) -- and 18 years later the 64-year-old "Django Unchained" actor at a benefit gala earlier this month (right).

After winning the Miss USA crown Erin Brady did what any starving beauty queen would do -- EAT ... well, kinda.

Our beauty queen spies tell TMZ ... Erin keeps her body right and tight by eating healthy (like all the time) ... which is why the 25-year-old noshed on a beet salad and spicy tuna on crispy rice as her first post-pageant meal.

Gorging on a burger didn't even cross Erin's mind ... she's a sweet over salty person. But the one thing she is craving: a hot fudge sundae, with ALL the toppings ... but for now, that's just unrequited love.

45-year-old Tanning Mom has entered rehab for alcohol abuse, TMZ has learned.

Sources close to Patricia Krentcil -- who famously faced child endangerment charges last year after allegedly putting her 5-year-old in a tanning booth -- tell us she entered Lukens Institute in Palm Beach Thursday night.

We're told Tanning Mom realized she had hit rock bottom after she was placed in detox for 30 hours at an airport in Minneapolis last week ... for being way too drunk to fly.

Of course, TM has had a few public drunken incidents -- last August she was a wasted, stumbling, panty-flashing mess at a gay nightclub in NYC. 'Memba that? So it's not a huge surprise.

As for why she ended up at Lukens -- a rehab center endorsed by Michael Lohan -- we're told TM reached out to Michael about treatment because the two went to high school together ... and she heard Michael mention Lukens' unique treatment and success in a recent interview.

Even though Petra Nemcova (left) and Stacy Keibler (right) are both models, actors, 33 years old and flawlessly posing for a photo in NYC together -- there is still one burning question that must be answered truthfully.

Tanning Mom's attempted sexy beach romp had some people at TMZ -- who will NOT remain anonymous -- proclaiming her bangable!

And don't get us started on "Backdoor Teen Mom" Farrah Abraham's new boobs.

Selena Gomez has the best problems in the world -- her brand new luxury automobile is so fancy ... she can't figure out how to get gas in it.

But you gotta see who helped her stick it in ... the gas tank.

Reese Witherspoon is a little preoccupied witherface -- because she just sued a jewelry company for using her mug in its ads.

Reese filed the lawsuit against Marketing Advantages International -- which runs the jewelry website Emitations.com -- claiming it exploited her name and face to sell jewelry and other stuff, including a knockoff of her engagement ring.

The deal breaker ... Reese insists she never gave the company permission to use her to hawk its wares.

The sun wasn't the only thing that was hot in Bali yesterday -- Ashley Greene and Vanessa Hudgens went two pieces on the Indonesian island.

The actresses sunned themselves in barely-there bikinis while attending the Oakley Pro Bali surf competition. Ashley even took some surf lessons herself.

We'd say more ... but a picture is worth a thousand words.

James Gandolfini was in the market for a mysterious new ink job before his death -- dropping by an L.A. tattoo parlor earlier this month ... and promising to return with a special order.

TMZ has learned Gandolfini visited T-Man Tattoo in Studio City on June 1st -- and the owner (pictured above) tells us, the actor was extremely excited about a new tattoo he was planning.

Gandolfini didn't tell the owner what he wanted to get done -- but said he just moved to the neighborhood, and promised to return later this month for a full tat session.

The owner says Gandolfini was in great spirits during the visit.

Like a turtle without his shell, rock-n-roll god Slash hit the pool in Ibiza this week ... WITHOUT HIS TRADEMARK TOP HAT!!!

The former Guns N' Roses guitarist is vacationing off in Spain with his family ... just like they did back in 2012. Dude looks good.

Meantime, here's a photo of Axl Rose at a yard sale in New York this weekend. He looks ... fine?

She already (kinda) redeemed herself for that infamous pageant flub -- so yesterday, we decided to pelt the beautiful Miss Utah with some brain-twisting riddles instead ... and she actually did pretty damn well.

21-year-old Marissa Powell had just touched down in L.A. for her appearance on "Jimmy Kimmel Live" -- and while she was at the airport, we asked her a bunch of questions to test her wits on the fly ... such as the classic "Who is buried in Grant's tomb?" and "What can you put in a bucket of water to make it lighter?"

She doesn't exactly get them right, but she doesn't exactly get them wrong either. Then again, she could probably say anything and we'd be happy.

Mariah Carey is either a 6 or a 10 on the hot scale depending on which photo you're looking at from her Italian vacation. Not that we're complaining about bikini pics.

Grazie, Mimi!
