It looks like Blake Lively isn’t having much trouble recovering from her recent split with Leonardo DiCaprio!  In fact, just this weekend she was seen with her Green Lantern co-star Ryan Reynolds leaving his apartment in the early morning.

The duo started seeing each other right after Blake and Leo’s split, and it all started with a hot, early morning make-out session at a train station.  Since then, Lively has been visiting Reynolds on weekends while he films a movie in Boston.

Since both of these hots stars are fresh out of relationships (Reynolds officially divorced Scarlett Johansson in July) – do you think they’re keeping things casual, or getting very serious, very fast?!  Let us know on Twitter or in the comments section!
