The news comes on the heels of several reports the 36-year-old crooner flirted behind the back of his 38-year-old actress wife.

Ever since his song Blurred Lines became a breakout hit in July 2013, the crooner has been caught in a series of bad situations.

Soon after Miley Cyrus twerked in his face and rubbed a foam finger on her private parts as she backed into him during the MTV Video Music Awards in August, he was caught with his hand on blonde socialite Lana Scolaro's derriere.

The inappropriate image was captured with the help of a mirror behind the married star as he smiled innocently for the camera.

Also eyebrow raising was his late January flirtation with an exotic beauty inside the Parisian nightclub Club 79.

The singer was spotted embracing the looker, who had big hair and flashed a black bra. And then he was seen dirty dancing with her, grinning from ear to ear. Paula was nowhere in sight.

Though the longtime couple were seen arm-in-arm on January 25 at a Clive Davis party, just weeks later he was spotted without the Mission: Impossible - Ghost Protocol knockout when he went shopping with their son Julian, aged three, in West Hollywood on February 13.

Though they were man and wife for almost a decade, they met when he was only 14-years-old.

Five years after their 2005 wedding they welcomed Julian.

In 2013 the son of actor Alan Thicke said of Patton, 'We're pretty sure we've loved each other for a few lives.'

Thicke was also in the news Sunday after a student group asked Boston University to cancel his upcoming concert, according to FoxNews.

The group is claiming his Blurred Lines hit song - which he sung at the VMAs with Cyrus - are sexist.

'Lyrics such as, "I know you want it," explicitly use non-consensual language,' the petition said. 'And while watching the extremely explicit video, the insinuations grow from subtle to explicit to obnoxious.'
