Rep. Gabrielle Giffords (D-Ariz.) made her first public appearance Monday since being shot in January.

Giffords showed up unannounced at a ceremony for her husband, retiring Navy Captain and astronaut Mark Kelly.

Seated in a wheelchair, Giffords was rolled into at theater in the Houston Space Center, according to Space.com, where Kelly was waiting for her.

She stood to hug and kiss him when he received the Spaceflight Medal, according to ABC News.

The event was in honor of the space shuttle Endeavour's final mission, which Kelly commanded in May. The medal is awarded to commanders of successful missions.

At the ceremony, her hair "was much shorter than in previously published photos. She was wearing glasses, a beige scarf, a light shirt, jeans and sneakers. She smiled and waved to the crowd," ABC News reported.

Giffords was released from TIRR Memorial Hermann hospital on June 15 and is undergoing outpatient therapy there. She and Kelly also recently signed a book deal.
