According to gossip blog Radar Online, Khloe Kardashian has been offered a whopping $250,000 to take a paternity test to determine if she really is a full-blood Kardashian, or O.J. Simpson’s spawn.

The mystery surrounding the real identity of Khloe Kardashian’s biological father can be solved with a simple DNA test, and RadarOnline.com has learned there’s a $250,000 offer on the table.

Sirius XM Satellite personality Gregg ‘Opie’ Hughes of The Opie & Anthony Show announced on Tuesday morning that he would ante up a quarter of a million dollars if Khloe, 27, would take a DNA test to prove that the late Robert Kardashian is her father.

If Khloe accepts, the $250,000 will be donated to a charity of her choice.

We’re not sure if O.J. Simpson was offered money to take a paternity test, but he sure could use the cash. His $500K Miami home is in foreclosure and it looks like he might lose the house while he serves his prison sentence.
