Jennifer Aniston Cozies Up to Former Fling

Aniston hits the town with another man for the second night in a row

Jennifer Aniston is not one to be photographed with Lindsay Lohan's leftovers and let the story sit around too long.

After dining with LiLo ex Harry Morton Wednesday at The Sunset Tower Hotel, Jen was papped last night having a romantic dinner date at Madeo in West Hollywood with another familiar gentleman.

So who's the guy?

None other than rumored boyfriend ('tho we just think more-than-friend) Chris Gartin.

Jen and Chris enjoyed a three-hour dinner at Madeo, where onlookers tell us they very much looked like a couple.

"They were on a date," says a fellow diner. "She was all cozied up to him and they were talking closely and laughing."

Our source says the two arrived at about 7:30 p.m. and sat at a table secluded from the main dining area. When they left around 10:30 p.m., our source says the two covered themselves with a sheet in their chauffeured car to avoid the snaps of the 15-plus paparazzi waiting outside.

But this isn't the first time these two have been spotted out together.

Chris, 42, and Aniston, 41, were seen on two dinner dates earlier this summer, one at Soho House West Hollywood and another at Jen's favorite hang, Sunset Tower, in July.

So what exactly do we know about Gartin? Well, he's also a friend of David Arquette and Courteney Cox, and he's got a True Blood connection (so Jen, we may really be getting on board with your latest fling choice).

So what's up with these two?

We asked Gartin's rep, and have yet to hear word one. However, back in July, Chris' rep told E!, "No comment."

We don't think these two are bf-gf status yet, but he's cute Jen, no harm in a last minute summer fling!
