Alan Thicke got candid during a recent interview with Us Weekly magazine, revealing his son's songs provide the soundtrack to his lovemaking when he and Robin's stepmother Tanya Callau are having sex.

Alan revealed, "When we do get freaky, we love Sex Therapy."

Callou, Thicke's wife of 10 years, added, "You have to admit, it's a great song to get in the mood."

But the candid confession didn't sit too well with the Blurred Lines hitmaker, who tweeted, "Dad, I heard what you said to @usweekly... I need you to give back all of my music. Immediately."
