Chris Brown's Panty-Dropping Fan ... Thong Was NOT Used

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.

Ray Allen South Beach Is Where It's AB

This is Miami Heat star Ray Allen on a beach -- and yes, those are his rippled ab muscles ... all 100 of them.

The 10-time NBA All-Star took his talents -- his gleaming, chiseled torso -- to South Beach over the weekend to ride jet skis with friends.

The NBA champion Heat desperately want 37-year-old Allen back next season for his clutch 3-point shooting (see Game 6 of the Finals).

But he clearly has much more than that to offer Miami.

The Rock's 'Hercules' Diet 7 Meals a Day 3 lbs of Meat, 14 Eggs!!!

If you're wondering what it takes to look like The Rock (aside from ridiculous genetics) the new "Hercules" star just revealed the diet he maintains to play the son of Zeus -- and it's unbelievable.

Rock just posted the breakdown on Twitter -- and it includes 7 full meals with ridiculous quantities of food, including rice, 14 egg whites, all kinds of vegetables, and more than 3 POUNDS of meat.

It's been working too ... Rock's been posting pics of himself during filming (above) and he's more jacked than ever.

Unfortunately, you can't just eat like The Rock to look like him ... you kinda have to go to the gym too.

Maybe tomorrow.

Eddie Murphy's Old Chick vs. New Chick WHO'D YOU RATHER?

Here's Eddie Murphy's 45-year-old ex-wife Nicole Murphy on a beach in Miami yesterday (left) -- and 34-year-old Australian supermodel and current Eddie Murphy girlfriend Paige Butcher on a beach in Hawaii one week earlier (right).

Who'd You Rather?

Both are incredibly sexy... but only one is a mother of five.

The question is...

Ying Yang Twins New Track Dedicated to Miley's Ass

0-75wsrzve

Miley Cyrus is God's gift to twerking ... at least according to the Ying Yang Twins who wrote an entire song about her booty-shaking greatness -- and TMZ has the track.

Kaine and D-Roc tell TMZ, they were inspired to make a tune in Miley's honor after learning she was a fan via Twitter -- and due to her transition from Disney princess to a derriere-popping powerhouse.

They tell us, "Our fans have been starving for some authentic twerk music. Seeing that Miley Cyrus wants to show the world she is grown by twerking, we decided to give her a little help."

You can listen to the lyrics yourself, but here are a few gems:

Do the Miley Cyrus rock wit it
Wiggle wiggle jiggle jiggle shake that s**t
All the n***as saying can she take that d**k?

Freaky b****es shakin ass on the pole
Do the Miley Cyrus b***h and get low

Miley Cyrus, ooh she wildin'
The way she shake her ass keep a n***a smiling'

With her camel toe she steal the show
Put her p***y in yo face like a freaky ho

Now, heeeeere's Miley (and her butt):

Miss USA Erin Brady Gets Fishy After Winning Crown

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.

Tanning Mom Swimsuit Pics Are ... Hot? Maybe?

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.

Farrah Abraham & Tanning Mom Topless Bikini Showdown Battle of the Bulges

It's the boobie battle you've all been waiting for -- 22-year-old "Teen Mom" porn star Farrah Abraham (with her brand new D cups) and the legendary Tanning Mom (with her genuine leather speed bags).

It's actually a hilarious coincidence ... Farrah and 45-year-old Patricia Krentcil both posed for topless photo shoots on the beaches of Malibu Thursday.

Malibu beaches are a hot spot for celeb photo shoots, so it's not that surprising they showed up around the same place -- but it's incredible they BOTH decided to drop their tops.

Who'd you rather?

So we gotta ask ...

Ashley & Vanessa Tiny Bikini Time ... In Bali

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.

Slash No Shirt, No Shoes ... NO TOP HAT???

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?

Maksim Chmerkovskiy Kate Upton Mystery Solved

0-has1yyz5

We now know what in the Hell Kate Upton was doing hanging out with "Dancing With the Stars" dude Maksim Chmerkovskiy -- and we're still not happy about it.

As we previously (and jealously) reported ... Maks and Kate were spotted leaving a restaurant together in NYC last week.

So, of course we've been wondering how someone known as the "bad boy of the ballroom" ... managed to bag the hottest chick on the planet.

Well, we ran into Maks at LAX, sans Kate, and asked if they're, y'know ... banging?

Let's just say we feel a little better ... for now. But not much.

Mariah Carey Kinda Hot or SUPER Hot?

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!

Colin Kaepernick TANKED In Los Angeles

49ers QB Colin Kaepernick is totally jacked up for next season -- after losing the Super Bowl this year -- showing off his beefy man arms in a black tank top today during a sunny stroll in L.A.
