News just broke today of the surprising split between Courteney Cox and her husband of 11 years, David Arquette, but there were tell-tale signs weeks ago.

On October 6th, we spotted David heading into an office in Beverly Hills without his wedding ring, looking very somber.

Apparently, the couple separated some time ago but managed to keep their marital troubles out of the spotlight.

"It's not a secret that they've had their share of problems over the years," a source tells Us. "But they fought hard to make it work. They went to therapy. There's no ill will there, they just grew apart."

The couple has one child together, Coco, 6.
