Jen Aniston -- Credit Card Situation Was 'Not Cool'

Jennifer Aniston -- one of the  mega-stars allegedly scammed by a Beverly Hills "skin artist" who was arrested yesterday -- claims the whole situation was "not cool."

Aniston just appeared on "GMA" -- and explained, "We had a situation that was not cool so I just stopped going to her."

As TMZ first reported, U.S. Secret Service agents busted Maria Gabriela Perez yesterday for allegedly "skimming" credit card info from her famous clients -- like Aniston, Liv Tyler and Melanie Griffith -- and making more than $200k worth of fraudulent charges.

Aniston told GMA that her damage "wasn't to the extent of the other girls" ... but noted, "I knew something like this would eventually happen because there's no way you can get away with that. It's terrible."
