Serena Williams dating coach Patrick Mouratoglou?

Earlier this week, Serena Williams appeared on Late Night with Jimmy Fallon and broke out into an impromptu rendering on Air Supply's All Out of Love. But photos hit the web Thursday that would seem to suggest otherwise.

Serena was papped (busted by paparazzi, duh) walking arm in arm with Patrick Mouratoglou, head of the Mouratoglou Tennis Academy this week in Paris, where Serena trained after her shocking first round loss at the French Open in May. The 42-year-old Mouratoglou, who has coached Jeremy Chardy, Aravane Rezai, and Grigor Dimitrov, has since been with her team serving as an adviser.

"I love Paris and I spend a lot of time there," Serena said when asked about training at the academy. "I have a place there. I've been kind of almost living there a lot. I found a great facility and I know Patrick and he's a great guy. I loved working with him while I was in Paris."

Now I'm not saying anything cause-and-effect here, but since training at Mouratoglou's Academy, Serena has lost only one match, winning Wimbledon, the Olympics and the U.S. Open.

Here's a tweet Mouratoglou sent after Serena clinched her 15th Slam title at the U.S. Open on Sunday.

Now I know what you're thinking: They're just walking arm in arm down a street! Pictures can be taken out of context! He's married! Maybe they're just close!

All fair and measured responses and I confess, that's how I reacted as well. But then...
