R&B singer Robin Thicke and his wife, actress Paula Patton are facing issues with the IRS. The IRS filed a $492,583 tax lien against the couple, according to the Los Angeles Recorder of Deeds. The couple claim they had no idea of any taxes owed. "They were just made aware of the issue and it is being taken care of immediately," a rep for the couple said.

Robin Thicke's latest album, "Love After War," is doing well on the R&B charts, and Paula Patton is currently starring in Mission Impossible: Ghost Protocol.
