Ben Affleck & Jennifer Lopez hang out in Montana, fans ask 'Is Bennifer back?'

Bennifer may just be making a comeback after 17 years. 

Exes Jennifer Lopez and Ben Affleck are sparking romance rumours after their holiday pictures from Montana went viral on social media.

The duo was spotted riding in a car together after Jennifer called off her engagement with Alex Rodriguez. 

JLo and Ben were engaged in 2002 and postponed their 2003 wedding days before they were set to walk down the aisle, and then officially split by January 2004.
