Christina Aguilera is one hot momma.
The singer turned heads at her first public appearance since giving birth when she performed at the Breakthrough Prize Awards on Sunday.
The “Beautiful” singer, who gave birth to a daughter, Summer Rain Rutler, on Aug. 16, looked stunning in a long-sleeved, floor-length red Rubin Singer dress.
The 33-year-old completed her look with blonde, flowing curls, Christian Louboutin pumps, red lipstick and her favorite accessory – fiancée Mathew Rutler.
Aguilera performed a rousing rendition of “Beautiful” at the awards show, which was hosted by Seth MacFarlane and honored 14 scientists who are changing the world.
Along with baby Summer Rain, Aguilera is the mother of 6-year-old son, Max, who she had with ex-husband Jordan Bratman.
