paula patton lax

*Paula Patton is rarely spotted without a smile, and today was no different, even as she goes through a very public separation with her husband, Robin Thicke.

But one thing was noticeably missing from the actress as paps swarmed her at LAX…her wedding ring. [Watch here.]

As previously reported, the couple announced they were splitting earlier this week. Today, TMZ reports the issue may have been sparked by Robin’s VMA performance with a twerking Miley Cyrus and headline-making behavior with other women.

Robin has pulled out all the stops to save his marriage — canceling several tour dates — but Paula’s not budging.
