She is known for her fondness for motorbikes along with her love of a distinctive outfit.
And Pink was combining the two passions on Saturday, as she joined hundreds of bikers at the Ride To The Flags charity event in Malibu to honour fallen heroes in the military, police and fire departments who died on 9/11.
Dressed in a striped jersey dress with a huge slit up the side along with tight black trousers, Pink took on the role of the Honorary Grand Marshall for the annual event.

Looking like a genuine biker chick, the Get The Party Started singer wore heavy black boots for the occasion, with a pink and white patterned helmet for safety.
Proving that she doesn't do anything just for show, she rolled up on a powerful looking black Harley Davidson that would look at home in any biker gang.
'I'm out at @ridetotheflags this morning - an amazing charity motorcycle ride to support injured marine Sgt. James Carey. Donate if yu can!' she tweeted on Saturday.

The charity ride was expected to attract 1,000 bikers who followed the route from the Naval Base at Point Mugu in Ventura County to the 9/11 memorial at Pepperdine University in Malibu.
After watching a moving memorial service, they traveled in a mass along the 40-mile stretch of the Pacific Coast Highway to the memorial park where 2,977 flags flew overlooking the ocean, each one representing a life lost in the 9/11 attacks.
Pink enthusiastically met many of the participants - from burly tattooed bikers to young children - as she strode confidentially through the crowd with her helmet still on her head.
