Robin Thicke is a married man, but fans might have thought he was single after the way Miley Cyrus gyrated on him during Sunday’s VMA Awards show. Thicke, 36, joined the 20-year-old former Disney Channel star on stage after she performed her latest chart-topper, “We Can’t Stop,” for a version of his summer hit “Blurred Lines.”

Wearing latex underwear, Cyrus stuck her tongue out as she twerked on the 36-year-old crooner, nuzzled his neck, and touched his groin with a giant foam hand. What did Patton think of the raunchy performance, which made headlines Monday?

Sources tell TMZ that the 37-year-old was completely fine with the performance, especially since there were “tons of rehearsals” prior to Sunday and nothing unexpected took place. Regardless, Cyrus shocked audiences in Brooklyn's Barclays Center, the award-show venue, and across the country. Most Twitter reactions addressed shock that Cyrus danced on Thicke and touched him inappropriately—not to mention the latex underwear. Cyrus’ fiancé, meanwhile, has kept silent about the performance, and though the singer wore her engagement ring at the show, it is rumored that the couple is heading for a split.

Australian actor Liam Hemsworth proposed to Cyrus in May 2012 with a 3.5-carat diamond ring, but it's been speculated for the past few months that Cyrus and Hemsworth have called their relationship off. They began dating in 2009 after co-starring in the film “The Last Song.”

Earlier this month, Cyrus and Hemsworth reunited for the premiere of his latest movie, "Paranoia," in Los Angeles, amid allegations that the couple is on the rocks.

She looked quite happy as she posed on the red carpet with Hemsworth, who kept his look simple with a gray-and-black suit. But a source told Us Weekly that "Miley and Liam acted like they didn't even know each other the entire night. She was wearing her ring, but they acted as if they were strangers."
