Dame Kelly Holmes stunned in silver as she hit the Attitude Awards red carpet at London's Roundhouse on Wednesday evening.
It marked a huge milestone for the Olympian, 52, who bravely came out as gay after 34 years in silence in June.
Dame Kelly joined a host of stars at the ceremony which celebrates people working tirelessly in the LGBTQ+ community.
The athlete beamed from ear-to-ear as she hit the red carpet alongside the likes of Ellie Goulding, Perrie Edwards and Spice Girls' Mel C.
Dame Kelly looked gorgeous in a one-shouldered silver floor-length dress which featured a pleated skirt.
She styled her blonde locks in a high quiff and amped up the glamour with a polished make-up look.
Speaking during Pride month, the two-time gold medal-winning Olympic champion said she realised she was gay at the age of 17 after kissing a fellow female soldier, and that her family and friends have known since 1997.
She told the Sunday Mirror: “I needed to do this now, for me. It was my decision. I’m nervous about saying it. I feel like I’m going to explode with excitement.
“Sometimes I cry with relief. The moment this comes out, I’m essentially getting rid of that fear.”
Dame Kelly also revealed she struggled with her mental health because of having to hide her sexuality, and that she had to keep several same-sex relationships she had during her time in the Women’s Royal Army Corps secret, for fear of being court marshalled.
Until 2000, it was illegal for gay, lesbian and bisexual people to serve in the British Army, Royal Navy and RAF – and Dame Kelly feared she would still face repercussions for breaking that law during her time in the forces.
She contacted a military LGBTQ+ leader in 2020 to find out if she could be sanctioned for breaking Army rules and was told she would not be.
She said: “I felt like I could breathe again, one little call could have saved 28 years of heartache.”
Dame Kelly also set up a charity in 2008, created to support retired athletes to transition out of their sport, and to create mentoring programmes to inspire young people from disadvantaged backgrounds into sports.
She has also started to make a documentary about her experiences called Being Me, where she talks to LGBTQ+ soldiers about their lives in the military now.
