Jennifer Garner reportedly turned down the role of Pamela Ewing in the forthcoming Dallas movie, after discovering her husband, Ben Affleck's ex-fiancee
Jennifer Lopez had signed to star in the remake.
Garner started dating Affleck in July 2004, seven months after he ended his high-profile engagement with J.Lo.
The Daily Mail claims Garner was in talks to play Bobby Ewing's wife Pam, but backed out when she realized Lopez would be playing JR's alcoholic wife Sue-Ellen.
"Jennifer Garner was really keen to be in Dallas, but I think she felt there would be a bit of a strain between them on the set and that could have led to awkward situations. Both are totally professional, but there might have been a certain 'atmosphere' and Jennifer Garner didn't need to go there" a source says.
