We certainly were surprised that these long time exes got so friendly so quick that they headed off on a romantic snow-cation just moments after having been seen together for the first time, but now it seems that they’ve been rekindling this flame for months!

Via TMZ:

Sources with direct knowledge tell TMZ … Ben and J Lo were in very regular contact by email starting in early February when she flew to the Caribbean to begin filming “Shotgun Wedding.” We’re told the tone of the emails wasn’t just friendly … but more loving and longing for Jen.

For instance, after seeing pics of Jennifer in the D.R., he wrote to tell her how beautiful she looked, and how much he wished he could be down there with her. Of course, he was busy at the time in Boston, shooting “The Tender Bar” with George Clooney — and she was still engaged to Alex Rodriguez.

Our sources say the emails also referenced J Lo’s love for Ben’s writing, and included a line about him being able to “own her heart” with his pen.

We’re told they continued emailing each other, back and forth, for the duration of J Lo’s shoot … which wrapped in late April.

As far as our sources know, there was no physical contact or rendezvous between them during this time, but the emails do add context to how they seemingly got together so quickly.

Well hey – sometimes you just have that ex that still gets ya going, and that seems to be the case here! Ben and JLo – the 2000s dream team is back together!
