Lopez mad with Aniston over film plans?

Jennifer Lopez is said to be angry that both she and Jennifer Aniston are making films about trying to get pregnant.

Lopez, who is returning to the big screen after taking a break to focus on music and motherhood, is involved in a movie called Plan B about a woman trying to conceive.

However, Aniston is starring in a film on the same subject called The Baster.

"The last thing J-Lo wants is to have Aniston overshadow her. There’s been some mud-slinging, with J-Lo claiming Jen took her idea," an industry source told The Mail On Sunday.
