Earlier we reported Brit was going to be engaged tonight, but it looks like it’s already happened! Brit just posted a message to her Facebook that read, “OMG. Last night Jason surprised me with the one gift I’ve been waiting for. Can’t wait to show you! SO SO SO excited!!!! Xxo.” Sounds like he put a ring on it! More info below.

Sources close to the couple tell us … Jason organized a MASSIVE celebratory dinner tonight at the Chocolate Lounge at the Sugar Factory in the Paris Hotel … because Brit Brit LOVES chocolate.

We’re told there will be a chocolate fondue and all the men will get chocolate truffle cigars.

After dinner … the gang is set to go to Chateau nightclub and party the night away.

We’re told everyone involved in the fiesta has received specific marching orders — anything Britney wants, Britney gets.
