How are you helping out the Hurricane Sandy relief efforts? Donating blankets and canned goods? Taking trips out to Staten Island to rebuild damaged houses? Bringing generators to people without power? That's good and all, but you're still not as much of a philanthropist as Madonna, who last night flashed her ass at Madison Square Garden to raise money those affected by the storm.

As E! tells it:

On Monday night at her MDNA concert in New York City, the Material Girl announced that she is "showing [my] naked ass for Hurricane Sandy victims," encouraging her audience to throw money at the stage as part of her fundraising efforts.

"If you are going to look at the crack of my ass, you better raise some cash," she told her adoring crowd.

No word on how much money Madge raised, but MTV describes "bills of all sizes rain[ing] onto the stage." Proof she's still got it!

This was Madonna's second time exposing her pentagenarian rear last night; earlier in the set the pop queen capped off yet another "Express Yourself"/"Born This Way" mashup by lifting her skirt and proclaiming "She's not me." And in Gaga's home turf no less! This feud will truly never die.

Madge also spent the day in Rockaway Beach raising awareness for hurricane cleanup, but there's a reason this site has a "Naughty Bits" tag and not a "Philanthropy" one.
