Radio host Bubba the Love Sponge Clem is trying to lure Casey Anthony's parents to appear on his show for $25,000.
The Sirius-XM host's spokesman said the offer was extended this week.
George and Cindy Anthony's attorney says he wasn't approached, but the couple doesn't accept money for interviews.
The two have lived a chaotic public life since granddaughter Caylee Anthony went missing in 2008. The Anthonys freely gave interviews at first, urging the public to help find the girl.
But the couple tried to withdraw after their daughter was arrested and charged with murdering the toddler. The media and members of the public camped out at their home for months, causing frequent arguments and tussles.
