Alan Thicke defends Robin's raunchy MTV VMAs duet with Miley Cyrus

Alan Thicke is always pulling for his 36-year-old son, Robin Thicke, the man behind what was arguably this summer's biggest hit, "Blurred Lines."

"I'm personally pulling for Robin Thicke at the VMAs," the 1980s TV dad told MTV several days before Sunday night's award show. "Because, well, he's been like a son to me."

As it turned out, Robin walked away with the night's most-talked-about performance, in which a scantily clad Miley Cyrus gyrated around the stage, grinding up and down his body while performing suggestive acts with a foam finger. Meanwhile, Thicke wore a black-and-white striped suit that garnered comparisons to Beetlejuice.

Cyrus' provocative dance moves sent shockwaves through the media world, and even prompted a statement from the Parents Television Council.

"MTV has once again succeeded in marketing sexually charged messages to young children using former child stars and condom commercials -- while falsely rating this program as appropriate for kids as young as 14. This is unacceptable," the organization said in a statement.

On Monday, Alan took to Twitter in defense of his son's artistic collaboration with the 20-year-old former Disney Channel star.

"Anyone expecting the VMAs to have 'Growing Pains' sensibilities does not watch videos and should be familiar with content before watching with children," the 66-year-old actor tweeted. "Don't complain, supervise!"

Robin has made no mention of the controversy, but called his performance "dope."

That was dope. Shout out to @MileyCyrus @kendricklamar @2chainz #VMA pic.twitter.com/Lva7RV8tAG
