Courteney Cox A dog may be man's best friend, but a woman's best friend (well, one woman's) is Courteney Cox!

Courteney showed up at the Marley & Me premiere to support her gal pal's most recent film, which looks to be the big screen hit that Jen's been waiting for.

Courteney and Jen have certainly been through a lot together during their fourteen years as Friends, and it's great that Courteney can see Jen through these good times after all the recent bad ones.
