Pop songstress Ke$ha took a break from rocking the mic to go on a relaxing bike ride with her boyfriend Brad Ashenfelter Sunday in Santa Monica. Click through the gallery to see her bare her buns and flip the bird!


Ke$ha was ready for action in a bright swimsuit and black short shorts.

She squinted to see what was on the horizon -- or maybe she just had glitter in her eyes!

Those shorts looked like a wedgie waiting to happen!

Ke$ha gave her boyfriend not one, but TWO middle fingers.

Her booty was too much for her tiny shorts -- adding fuel to rumors that she may have gotten butt implants!

Despite the flipping of the bird, Ke$ha seemed to be having a great time...


But the wedgie struck again!

Sun's out, buns out!
