Brit's old pal Sam Lutfi was out at Sunset One over the weekend, and X17 photogs had a chance to talk with him briefly.

When we asked if he missed Britney, without hesitation he said "of course!" He then said that he wanted to tell her that he hopes "she's doing alright and I miss her and everything!"

Awwww!

Think these two former BFFs will be reunited soon?
