met gala  Jessica Biel  Justin Timberlake If this is how good they look at a party, just imagine their wedding!

Justin Timberlake and Jessica Biel stepped out for their first post engagement appearance at the "Schiaparelli And Prada: Impossible Conversations" Costume Institute Gala in NYC last night, and the A-list couple really brought the glam! The Illusionist actress wore Prada for the big night, while her man opted for a classic Tom Ford tux.

For months the brunette beauty has hidden her sparkler from the public, but now there's no denying the SexyBack crooner is making an honest woman out of her. Aww! Their love definitely proved to be more than a rebound romance!

Rumor has it the pair is planning an Italian summer wedding, and we have a feeling the bash will be the hottest invite in town!

We wonder who will make it down the aisle first - Justin or Britney!
