35 Celebrity Enemies Who Used to Be BFFs
Jennifer Garner and Mark Ruffalo
13 Going On 30 is a tween classic. The chemistry between Mark Ruffalo and Jennifer Garner was so sweet that it’s crazy their on-set friendship never really got off the ground IRL. Talking to Andy Cohen on Watch What Happens Live, Mark revealed that Ben Affleck was actually the reason his friendship with Jen faded and that it made him sad. Sure, that doesn’t make Jen and Mark ~enemies~ but it does make Ben my enemy, so I say it counts.
