Length of relationship: A month, maybe?
Latest rumors: Just that these two are an item.
Chances their relationship will hit the one-year milestone: Surprisingly good! I say that because dear Leo is a serial monogamous modelizer. First he date a shit ton of models in his early-20s, then he was with Gisele Bundchen for five years, then Bar Refaeli for four. He dabbled in the actress pool with Blake Lively, but I think he missed the reassuring familiarity of a catwalker. This one could last until she's too old, i.e. 25 (she's 22 now).
