Madonna is always one to jump on the latest and greatest dance craze. During her New York concert, the Material Girl performed "Gangnam Style" with Psy.

The Korean singer, who flew to NYC from Germany for the show, rocked it out with the pop legend ... showing off his killer moves.

Seeing Madonna crawling through Psy's legs was a bit awkward, but we couldn't stop watching. You go, boy!

She put her rock hard body on display for a good cause!

During her concert at Madison Square Garden on Monday, Madonna did her part to raise money for the victims of Hurricane Sandy by stripping down for cash!

The "Express Yourself" singer asked the crowd to throw money on stage as she removed her top to reveal the words "No Fear" written on her back. As she performed her classic hit "Like A Virgin," the audience threw dollars at the Queen of Pop, who was more than happy to get scantily clad for a good cause.

"If you are going to look at the crack of my a--, you better raise some cash," she told the exuberant crowd.

The 54-year-old was motivated to help after witnessing the devastation firsthand.

"I went down to Rockaway Beach yesterday with my children, and we saw what was going on there, we saw the destruction. It was really sad, but we also saw amazing acts of humanity. People sharing with other people, people working hard, cleaning houses, handing out food, blankets, giving love," she explained onstage.

Madge isn't the only celeb with a big heart! Justin Bieber pledged to donate $1 of all New York concert ticket sales, and Lady Gaga donated a whopping $1 million to the Red Cross.

We wonder how much money The Material Girl raised?!

And the feud continues!

Madonna hasn't exactly shied away from taking swipes at Lady Gaga in recent months, and during her concert in Minnesota on Sunday, the pop icon took another jab at the "Born This Way" singer.

"I have the best fans in the world. So take that, Lady Gaga! You know, I invited her onstage to sing with me. But she turned me down. It's OK, I've been rejected before. It builds a little character," she announced onstage to the crowd.

Although Madge didn't reveal exactly when she extended the olive branch, it appears Mother Monster isn't interested in putting an end to the tension anytime soon.

The battle between the blondes ignited after the Queen of Pop dissed Gagaloo for the similarity between "Born This Way" and "Express Yourself."

We think Madonna needs to find a new way to keep her name in the headlines!

Madonna appeared on Ellen today and brought out a special guest - her son Rocco!

Madge was asked to select an audience member to dunk in the splash tank to help raise funds for Breast Cancer Awareness Month, and she volunteered her teenage son, who was backstage.

Shy Rocco chatted with the talk show host about his dance routine in his mom's concert and what it's like being the child of the pop sensation. When asked if Madge is a strict parent, he responds, "She's a good mother. Yes. That's all I have to say. She's very strict but in a good way."

After a couple tosses, the Queen of Pop finally gives up on hitting the bulls eye and let's the talk show host drench her 12-year-old!

Check it out!

Guess Madge is burying the hatchet!

During Madonna's concert in France on Tuesday, the pop princess dedicated a song to her rival Elton John! Before performing her hit "Masterpiece," the Queen of Pop told the crowd that the "Candle In The Wind" crooner was a "big fan" of hers. Then she added, "I forgive him."

Her nice gesture might have been on the sinister side, though! That particular tune won the 54-year-old a Golden Globe earlier this year, which sparked backlash when Elton's partner David Furnish claimed she didn't deserve to win.

The British chart topper fanned the flames of the feud earlier this month when he called Madonna a "fairground stripper" and claimed "her career is over."

Dedicating a song to someone is such a heartfelt gesture, but only if you truly mean it!

She may be 11 years away from collecting Social Security, but with an estimated fortune of $650 million and over 300 million records sold, Madonna is still a force to be reckoned with!

The pop superstar turns 54 today, and to celebrate her birthday and a quarter century worth of hits (since 1983 she's had 38 top ten singles!) we've decided to put together a photo gallery of our favorite snapshots of the Material Girl.

She is currently on tour to promote her 12th studio album, MDNA, and we've snapped her spending quite a bit of time with her latest boyfriend, 25-year-old Brahim Zaibat. She may not look like a virgin anymore, but the boys keep getting younger -- after dating 37-year-old Yankees star Alex Rodriguez in 2008 and 26-year-old Jesus Luz from 2008-2010, she started dating the French model/dancer 2 years ago.

Speaking of "Like A Virgin," remember this legendary performance from 1984?

Give me an A - A - R - P!

Madonna grabbed her red pom poms and hit the stage at Olimpiyskiy Concert Hall in Moscow.

The 53-year-old performer has been raising eyebrows with her onstage antics ... one, in which, she wrote the word "Pussy" on her back in support of jailed Russian punk band, Pussy Riot.

As a result of Madge's controversial act, police received terror threats. Despite the threats, the "Like A Virgin" singer has continued with her shows.

After all these years, Madonna seems to still be pushing the envelope.

Madonna fans beware!

The U.S Embassy is warning Americans of a serious threat being made by an unknown source to harm spectators and performers during the Material Girl's scheduled concert in Russia tomorrow.

Apparently the U.S Consulate General in St. Petersburg received a tip that there was significant cause for concern, and they are warning all citizens who attend the concert to "remain vigilant regarding their personal security."

The threats come days after Madonna voiced her support of jailed Russian punk band P***y Riot, which authorities believe could have contributed to the terror threats.

The concert is still scheduled to happen as planned. Nothing stops Madge from putting on a show!
