Why Is Courteney Cox a 'Cougar' with a Cane?

The Cougar Town star was spotted walking around the set of her ABC show Thursday with the help of a cane.
So what's up? Cox, it turns out, has a bum knee thanks to a recent surgery.
"The minor knee surgery was planned," a rep for the actress tells PEOPLE. "[The cane] will be written into one episode of Cougar Town but will not affect the production schedule at all."
The show, which is in production but currently on hiatus, will return to ABC for a special post-Dancing with the Stars episode April 18 (9:30 p.m. ET) and will be back on at its regular timeslot (Wednesdays at 9:30 p.m. ET) two days later.
"[Cox is] working every day," according to a source, who adds that the series will wrap in Los Angeles the first week of March, then the cast will go to Hawaii to shoot the season finale, which will air in May.

Courteney Cox might deny that there was any affair between her and Cougar Town co-star Brian Van Holt, but their behaviour at the show’s holiday party certainly has people talking!

E!’s Marc Malkin reports that a source claims that the pair was ‘inseparable’ throughout the party, and that;

“Courteney and Brian pretty much stuck together the majority of the evening.”

“There definitely wasn’t any hand-holding or kissing, but they did stay and stand together for most of the party.”

Well I’m pretty sure that they are good friends so it’s not that surprising to me that they were standing together throughout the party! Not sure if that would be enough for me to think that there was something else going on though. What do you think – does the fact that they stood together throughout the party mean that there’s something going on?!
