Singer Robin Thicke has been arrested in Manhattan for marijuana possession, the New York Daily News reported Friday.

Thicke, son of "Growing Pains" actor Alan Thicke and singer Gloria Loring, was spotted by cops smoking a joint in a Cadillac Escalade on East 21st street shortly after noon local time.

"He wasn't driving," a police source told the paper, "He was sitting in the car. He was arrested and a small amount of marijuana was recovered on him."

There was another passenger in the luxury SUV at the time but Thicke was the only person to be arrested.

His arrest follows his performance Thursday night at the Nomad's Way gala to benefit educational initiatives in Kazakhstan, hosted by Sigourney Weaver at the New York Public Library.

Thicke, 34, is a noted R&B singer-songwriter and has released five studio albums.

He has also written songs and produced singles for music heavyweights including Jennifer Hudson, Usher and Christina Aguilera.

He is married to "Mission: Impossible -- Ghost Protocol" actress Paula Patton, 36, and the couple has a one-year-old son, Julian Fuego.
