Could there BE another Rachel Green besides Jennifer Aniston?! Brace yourselves, "Friends" fans – another '90s TV starlet almost had the part. According to Access, Tiffani Thiessen revealed that she actually auditioned to play Rachel – and got pretty far. She said: "I was a little too young. A little too young to the pairing of the rest of them." She has a point. Tiffani was only 20 when "Friends" premiered in 1994, making her five to 10 years behind her would-be castmates.
