No, Singer Robin Thicke (born Robin Charles Thicke on September 15, 1977 in Los Angeles, California) does not suffer from diabetes, however his older brother does.
Brennan Thicke (born December 17, 1974, also in Los Angeles, California) was diagnosed with Type I diabetes some time in the late 1970s to early 1980s.
Their parents are actor Alan Thicke and vocalist Gloria Loring, and they also have a half brother named Carter William.
Robin taught himself how to play the piano by the age of 12, and took that talent forward to become a Grammy winning song writer later in life.
Robin is part of the big talk around town now because he's one of the new judges on ABC TV's new series Duets along with fellow judges Kelly Clarkson, John Legend and Jennifer Nettles.
