Jake Gyllenhaal is enjoying his success both professionallly and personally. The Source Code actor is now hooking up with 90210 beauty Jessica Lowndes, according to Us Weekly.

A source tells the mag Jake and Jessica were seeing sharing breakfast at New York's Greenwich Hotel. However, later the same day, the hunky actor reportedly went to a NYC party at the Bowery Hotel with someone else.

Although Taylor Swift and Jake split last year, the mag also claims Gyllenhaal took a "Swift look-alike" to NYC's Locanda Verde, however their interaction seemed "very friendly."

Aside from being smoking hot, Jake has the best personality. See his comedic side from this weekend's Saturday Night Live ... after the jump.
