Tax Man lien-ing on Robin Thicke, Paula Patton

Feb 27, 2012 at 1:23 p.m. ET

Celebrity couple Robin Thicke and Paula Patton have found themselves on the wrong side of an IRS lien. The federal government claims the singer and his actress wife failed to pay nearly $500,000 in taxes between 2009 and 2010.

Uncle Sam cometh for Robin Thicke and Paula Patton.

The handsome couple -- one an actress, the other a "blue-eyed soul" crooner -- forgot to save a slice of their financial pie for the federal government. Now the Internal Revenue Service (IRS) has come calling.

Tax officials say Robin and Paula, who wed in 2005, failed to pony up dough in 2009 and 2010. The oversight has left the award-winning Thicke and Patton -- who earned critical acclaim for her role in the 2009 hit Precious -- shamefaced as their California property was slapped with a lien this month.

According to official documents filed in Los Angeles last week, the couple owes the Feds $492,583.49 in back taxes. It is a debt the twosome is determined to settle, according to their camp.

"They've already paid more than half of this and they're working with the IRS to pay the rest," a rep for Robin and Paula said over the weekend.

This is the second spate of bad news to hit the Thicke household this month. On Feb. 17, Robin was arrested in New York City and charged with drug possession.

Police collared Thicke near Manhattan's Madison Square Park after two officers spied the 34-year-old lighting up a marijuana joint inside a black Cadillac Escalade.

The star was given a desk appearance ticket and released.

Thicke has admitted battling substance abuse issues in the years before his critically acclaimed album -- The Evolution of Robin Thicke -- hit the charts in 2006.

Robin is the son of actor Alan Thicke, who starred as patriarch Jason Seaver on the 1980s sitcom Growing Pains. He and Paula -- who were high school sweethearts -- share a son, Julian, born in 2010.
