Jennifer Aniston and Ben Affleck were co-stars in the 2009 movie, "He's Just Not That Into You". Both of them acted as couple in this movie.
A source revealed to In Touch Weekly, "Jen has definitely had a mini crush on Ben for years."
Aniston never approached him because both of them were not single at that time.
Source added, "As things pretty openly wind down between J. Lo and Ben, there’s a real opportunity for Jen [Aniston] to make up for lost time with Ben."
"There’s a very friendly and flirty open line of communication between them, plus a boatload of mutual friends — everybody from Jon Hamm to Sandra Bullock, who can totally see Ben and Jen becoming a couple down the road,".
