What a pair!

The ORIGINAL rebel, Madonna, posed with her younger counterpart, Miley Cyrus, at the 2013 Billboard Music Awards Sunday night at the MGM Grand Garden Arena in Las Vegas.

Madonna took home three prizes -- for Top Dance Album, Top Touring Artist and Top Dance Hall Artist. Wow!

Miley, meanwhile, made a splash in her super-sexy crocheted Balmain jumpsuit with black and while harlequin and lots of peek-a-boo pieces. And during the pre-show, the 20-year-old announced her new single "We Can't Stop" will debut June 3 on Ryan Seacrest's radio show. Can't wait!

Madonna was the last star to arrive to the 2013 Costume Institute Gala on Monday night, but as far as we're concerned, she was one of the only celebs who went all out and adhered to the punk theme.

Madge wore a dark wig, a grey studded tartan jacket by Givenchy Haute Couture by Riccardo Tisci and fishnet tights, and the 54-year-old singer accessorized with her 25-year-old boyfriend Brahim Zaibat. That's pretty rebellious, right?

Madonna and her four children, Lourdes, 16, Rocco, 12, Mercy, 8, and David, 7, made a visit to the Mkoko Primary School on Tuesday in central Malawi, and the famous family also spent some time at the orphanage where David Banda was adopted in 2006.

"I'm happy that David is back to see his brothers and sisters," Madonna told reporters. She added the photos above on Instagram and wrote, "With a Woman from Nijiti Village in Malawi where we have built 10 schools with Build On! Equal attendance Girls and Boys! YEAH!" Madonna is reportedly the single largest international philanthropic donor to the country.

Madonna and her children will visit a pediatrics hospital on Thursday and another orphanage Friday, but it's not clear whether she will visit the Kondanani Children's Village, where she adopted Mercy in 2009 after a nasty court battle.

Congrats girl!

Madonna is the newest member of the billionaire's club, thanks largely to her wildly successful MDNA tour and a string of savvy investments.

The singer was named the top earner in pop music in 2012 with an estimated $700 million fortune, but after grossing over $3 million in concert ticket sales, an additional $85 million on merchandising, and upwards of $100 million in entrepreneurial endeavors, the Material Girl is officially a Billionaire Girl!

Some of her non-musical projects include her perfume Truth or Dare, and her own line of Hard Candy gyms. The 54-year-old Queen of Pop also has her Material Girl clothing line in collaboration with daughter Lourdes, and has become an investor in Vita Coco water.

Life is good for Madge these days!

She's never been one to shy away from controversy, that's for sure!

Madonna joined Instagram mere weeks ago, but already the Instagram Team is sending her letters requesting she tone down her sexy snapshots!

Clearly not embarassed about the slap on the wrist, Madge decided to upload the letter in full to her account, followed by a picture of herself in a black wig and cleavage-baring green leather dress. Yikes!

Some of the things on their no-no list? Sharing photos that aren't your own, sharing photos that show nudity or mature content, sharing photos of illegal content, and sharing photos that attack individuals or groups.

We think we know which violations she's guilty of...

It could have been her sweaty cleavage shot, or it could have been her booty pic, but something has made the app administrators angry!

We wonder what her kids think of all this!

Madonna recently joined Instagram, and the pop singer hasn't wasted any time uploading personal photos that show her in various states of undress! Even though she's in her 50's, Madge sees no problem with showing off her sexy bod, apparently!

In her latest post, the Grammy winner shows off her enviable backside in a picture taken backstage before one of her concerts. In another snapshot earlier this week, the mother-of-four showed off her cleavage dripping with sweat after a workout. Yikes!

Not all her updates are of a sexual nature, though!

The blonde bombshell also showed off a Valentine's Day card from one of her kids that read, "Happy Valentine's Day. You are the best and you make me so happy. I love you Mom."

When you are the Queen of Pop, you can do - and post - whatever you want!

Er, maybe sexy isn't the best word, but she definitely got our attention!

Madonna joined Instagram on February 10, and while she started off with a few random concert shots, she later posted two saucy selfies. "Cheers motherf**kers! I'm on instagram," the 54-year-old singer wrote, followed by a snap of her sweaty boobs with the caption, "Addicted to sweat."

As you may know, Madonna and her trainer are launching a workout DVD series by the same name, and she recently said in a statement, "Addicted to Sweat is inspired by my workout regimen that I do consistently to take care of my mind and body. My trainer Nicole and I have created this program that has helped give me the body I have today."

Madonna and her personal trainer Nicole Winhoffer are launching a new DVD series called "Addicted To Sweat.”

Winhoffer told the Huffington Post, "In 2010 Madonna opened her first gym in Mexico City, and the idea for the opening was to teach a cardio class. She thought that would be a great idea, so we taught a class and the members loved it. She led the class and I was next to her. I always document the programs I do with her, and we went through my diary and she chose one of the programs to turn into the DVD, which she named 'Addicted to Sweat.'”

“Fitness is so important to her because she’s one to empower people," Madge's trainer added. "She is an example -- not just as a pop icon, but an example as a businesswoman, an entrepreneur, a woman that's in shape. The only way she is able to get through her day and schedule all her meetings and to be there for her children is to have a fit body. She makes time in her schedule for the workout. It gets her mind and body to connect. She always wants to be the best and everyone around her to be the best. Her fitness is the key. She’s the perfect example to share her workout with people around the world.”

Nicole says Madonna's gyms may be coming to the United States in the future, and she added that the queen of pop gives her stamp of approval to all aspects of the gyms and she even picks out the music and look of the DVDs.
