X17 XCLUSIVE - Brit's Mystery Manny ID'd!

Everyone's been trying to figure out who Brit's new mystery manny is and we think we've got it! A source tells X17online exclusively that Daimon Shippen's the man -- he worked as a production assistant on the movie "Road To Red," which starred Chris Blasman (???) -- a guy Brit was photographed with last week at the Chateau Marmont the night she wore the pink wig.

And here's the dirt on the alleged Mr. Shippen ... our source is telling us that Daimon was fired from his former employment agency, Galahad Security, because he allegedly owned a sex toy/porn website. He then went to a domestic service employment agency that doesn't regularly perform background checks ...

So are Britney and Daimon an 'item?' Our source says Shippen may not be into girls and second, that Britney's real "boyfriend" is named Sam.

Shippen is rumored to have an apartment in Santa Monica and we found reference to a Daimon Shippen competing in a Santa Cruz, CA triathlon last year at the end of September (listed as a Santa Monica resident) -- Shippen aged 34 as of that date. The mystery manny's a tough lookin' guy; makes sense to me!
