Farrah Abraham -- There's a New Man Knocking On My Backdoor

Seems James Deen may have a brand new eskimo brother ... a guy named Brian Dawe ... 'cause it appears B.D. is now dating "Backdoor Teen Mom" Farrah Abraham.

Dawe and Farrah were pictured on a romantic-ish stroll in Florida a few days ago -- with Farrah's child nowhere in sight.

Dawe has a website -- and says he's a DJ, who says he's "rocked the stage" with stars like Rihanna, Ke$ha, Avicii, Steve Aoki, Alesso, Travie McCoy, Lil Jon, Dev, Busta Rhymes, Trick Daddy, DJ Khaled and 2 Live Crew.

Good luck Dawe -- you've got some big ... really big ... shoes to fill.
