JUSTIN TIMBERLAKE HAS CONTINUED TO GIVE BRITNEY HIS SUPPORT DURING HER STRUGGLES LATELY AND HE IS RUMORED TO HAVE SENT THE FALLEN POP STAR A TOUCHING LETTER IN REHAB! HERE'S MORE:

"She could barely catch her breath to read the words. It was one of the most moving letters she had ever received. He poured his heart out. He told her he was sorry they fell in love so young, because if they’d fallen in love even just a few years later, he would’ve married her - and they’d probably have kids together by now. Justin let Britney know that she has his unconditional love and support. He offered to come visit her in rehab."
