Jessica Biel hit the red carpet at today's Met Gala with fiancé Justin Timberlake by her side. It's the third time Jessica has attended the Costume Institute Gala on the arm of JT. They also made a memorable pair at the bash in 2010 and 2009, when Justin was actually one of the event's co-hosts. This is the first time, though, JT and Jessica are there as an engaged couple, and Jess' is proudly showing off her engagement ring. Justin popped the question over the holidays, and the pair are said to be planning a big wedding for the northern Summer. This will be a great chance for Jessica to survey gown styles if she hasn't picked a wedding dress just yet. What do you think of her Prada look today?
