She admits the actors don't always get along
"In the beginning, it was innocent and fun" said Reed, who plays Rosalie Cullen, to Seventeen magazine "and we were like one big happy family - it was like being at sleepaway camp".
However things seem to have turned slightly sour since the first Twilight film.
"Then success comes along and changes the dynamic" continued the star "We're not all best friends, and we're not all going to hang out together after the final movie is done".
It was reported that Reed briefly dated Robert Pattinson when they first met, which might have created tension between her and RPatz' rumoured girlfriend Kristen Stewart.
