Liberty Ross & Jimmy Iovine -- Probably Banging Now

Kristen Stewart might get a thank you note for ruining Liberty Ross' marriage ... 'cause it seems LR has upgraded BIG TIME from adulterous Rupert Sanders to music honcho Jimmy Iovine

Liberty and Jimmy were seen leaving a NYC hotel together this morning -- amidst rumors they've been dating for the past couple of weeks.

The timing makes sense, since Liberty just filed for divorce from Rupert on January 25 ... 6 months after the "Snow White and the Huntsman" director cheated on her with K-Stew.

Iovine is a LEGEND in the music world -- he co-founded Interscope Records, worked with huge stars like Eminem and Lady Gaga ... and reportedly co-owns the ultra-successful Beats by Dre brand with Dr. Dre.
