She said back when she was on ATWT, she was so excited when she learned she would be playing twin sisters but later became bored with acting with herself. She wanted to experience her acting with other people.
I'm pretty sure the characters of Frannie Hughes and Sabrina Hughes were half sisters & cousins to each other not twins. Bob was the father of both and Kim was Sabrina's mother and Jennifer was Frannie's mother.
Which was when she made an appearance at the Kim and Bob's 25th anniversary I was surprised in a way that she wasn't playing Sabrina. As "Frannie" though she made a comment that she was going with Sabrina to Haiti to help with recovery from an earthquake. She could have just as easily played Sabrina or played both characters.
I didn't see her speech I'll look it up and see it for myself. If she did say that she was wrong.
Thats just my opinion...I could be wrong. -Dennis Miller
Yeah, I don't think she wanted to get into the details of her characters in her speech so it was just easier for her to say twins. The key was that they were sisters and she played both roles.
