But simply spotted at a wedding? We know that's not the whole story when it comes to J.T. and J.B.
So what's going on?
Well, sources close to the on-again couple say they are "definitely back on."
Duh, otherwise, ya don't go bike riding together.
But more importantly, we had to figure out why the heck Jess would let her ex back in her life after he was linked to a slew of Hollywood A-list hotties both pre- and postbreakup.
So did Justin "cry Jess a river" and finally decide Jess is "The One?"
After initiating the split in March, Justin began his campaign to woo Jess back in early July, a source close to the couple claims...conveniently after deciding that he had grown tired of chasing after costar Mila Kunis.
The timing fits perfectly since the then-exes were spotted together in early July at a barbecue in Brentwood, Calif., and while "there were no PDAs," this meeting seems to have marked the beginning of Justin's quest to win back Jess.
The Jess ‘n' Justin source revealed that after growing tired of Mila, Justin "spent the last few months trying to get [Jess] back. He missed her. They're back on. He went after her." Although the insider also insists that "they started taking it slow." Reps for the stars would not comment.
So while Jess has been busy in Toronto filming Total Recall, it seems that Justin has been taking full advantage of the break in his schedule to win back his longtime love.
But while Justin's Southern charm seems to be working (again) on Jess, we highly doubt the notorious player will change his ways for good.
As for you, Jess? You've openly admitted to wanting marriage and children in your future, and you're beautiful, smart and accomplished.
So why are you putting yourself through this again?
