Christina Aguilera is embroiled in a lawsuit over allegations bosses at her record label sampled a 1968 song in her track Ain'T No Other Man without paying the rightful owner.
The singer's hit single reportedly uses a beat from Dave Cortez and the Moon People's soul song Hippy Skippy Moon Strut.
According to legal papers, filed in New York, TufAmerica bought the exclusive rights to the original song in 2004, but Aguilera's label bosses at Sony made a deal with Codigo Music and the Clyde Otis Music Group to use the record.
Heads at TufAmerica are now asking a court to declare them the rightful owner of the song and are seeking damages, reports Tmz.com.
