Jennifer Lopez, Ben Affleck's blooming relationship 'Is Not a Summer Fling': Source

This love is here to stay.

Jennifer Lopez and Ben Affleck’s romance is going stronger than ever. The two recently enjoyed a tour of the Mediterranean on a yacht to celebrate Jlo’s 52nd birthday.

A source close to the couple told PEOPLE that the two are “very much enjoying their vacation” and it couldn’t be more true because Ain’t Your Mama finally decided to make her relationship with Ben Affleck Instagram official.

According to the source, JLo and Ben are taking their relationship seriously by discussing the hard things related to their future as well. The source further shared:

"This is not a summer fling. They are planning a future together. They have serious talks about how they can make it all work. Between their relationship, their kids and jobs, they know it will be tricky to balance it all."

"Jennifer is the happiest," the source added. "She keeps gushing about how amazing Ben is."

Ben, 48, and JLo first dated in 2002 after working together in Gigli. The spark between the two was reignited when they rekindled in April after their respective splits from Ana de Armas and Alex Rodriguez earlier this year.
