Christina Aguilera Makes First Red Carpet Appearance Since Giving Birth to Baby Girl Summer!

Christina Aguilera makes her first red carpet appearance since welcoming her baby daughter Summer at the 2014 Breakthrough Prize Awards Ceremony held at NASA Ames Research Center on Sunday evening (November 9) in Mountain View, Calif.

The 33-year-old entertainer walked the carpet with her fiance Matthew Rutler just about three months after giving birth – she looks amazing!

We have yet to see a picture of the newborn baby girl. Christina also has a son named Max, 6, from her previous marriage.

FYI: Christina is wearing a Rubin Singer dress, Christian Louboutin shoes, Broken English earrings and ring, and a Loree Rodkin ring.
