Looks like the lines of monogamy might have been blurred for Robin Thicke (sorry, we had to). Though the chart-topping crooner is married to actress Paula Patton — the two have a son, Julian, 3 — they’ve long dealt with rumors of an open marriage. And thanks to some recent photos of Robin cuddling up to a mystery woman in a Paris nightclub, these rumors aren’t likely to die out any time soon.

The “Give It 2 U” singer was snapped doing some dirty dancing and even seeming to go in for a kiss at Club 79 in the City of Lights, following a performance at the venue this week. His wife of 8 years was not in attendance. Kanye West was also in the club, though he wisely steered clear of the dance floor.

This isn’t the first time Robin’s come under scrutiny for associating with women that weren’t his wife while in night clubs. Back in September, a woman claimed that the star made a pass at her in a NYC hotspot, though she said they didn’t go through with anything because they kept being interrupted. "His hands were everywhere. He was grabbing me. He was like, 'I want to get you into bed!'" she asserted.

Robin and Paula have been married since 2005, though they’ve been together nearly two decades, starting from when they were teens in L.A.. And though they’ve weathered rumors of infidelity before (on his part) until now no photos have popped up. We wonder what Paula will have to say about her hubby now..
