Are there Wedding Bells for Justin Bieber and Selena Gomez?

While Justin Bieber and Selena Gomez aren't getting married, the two lovebirds attended a wedding yesterday (Thursday, December 8th) in Los Cabos, Mexico!

The "Who Says," singer was a bridesmaid for the wedding and looked absolutely gorgeous in a long blue gown while her "Baby" boyfriend opted for more casual with green capri pants and a while blazer.

Check out the pics from the super cute wedding!
