LOS ANGELES: Jennifer Aniston's representative has dismissed reports the actress will reunite with her FRIENDS co-star Courteney Cox in the second season of her U.S. TV hit Cougar Town.

The He's Just Not That Into You star was alleged to have signed up to make a guest appearance on the sitcom, following in the footsteps of her former Friends castmate Lisa Kudrow.

A spokesman for Aniston insists the rumours are false, although he has refused to rule out the possibility in the future.

The rep tells GossipCop.com, "At present there are no plans for Jennifer to be on the show. (But) never say never."

Aniston isn't the only former Friends star to turn down the offer - Matthew Perry refused to romance Cox for the new comedy in November (09).

But Cox shouldn't be too disappointed - Cougar Town, in which the star plays a middle-aged single mother on the hunt for a younger man, has been picked up for a second season by ABC network bosses.
