Paris was working it yesterday in sexy Agent Provocateur lingerie, shooting scenes for My New BFF at the Oceana hotel in Santa Monica. Girlfriend almost caused a traffic accident from gawkers driving by, trying to get a glimpse of the hottie on the balcony! After that she put on a hawt sequined dress to finish the shoot down at Duke's in Malibu.

Although she may have been working yesterday, sources tell X17online that she had just returned from a romantic getaway with BF Doug at the Montage in Laguna. No wonder she looked so relaxed - and happy! But Doug may have something to do with that part...

The couple had lunch the other day with Doug's parents and "they looked like a couple about to get married, lunching with her fiance's parents before a big wedding or something!," the source told X17online.

A new BFF, a new BF and soon a new fiance?
