Is Britney Mixing Business With Pleasure?

Britney claims that her relationship with super-realtor Robert Edie is strictly professional - but judging by these pictures of Brit and Robert enjoying dinner at the Four Seasons together, we're wondering if things are getting personal!

We just got these pix of the Queen B dining with the King of Celebrity Real Estate at her home away from home on Thursday night. We don't want to say for sure that Brit and Robert are definitely out on a date - after all, does the combination of mimosas and nachos scream "romance" to you?

Still - you can't deny that they're getting awfully cosy!
