The forward converted the winning penalty as the Lionesses beat Spain on spot-kicks on Sunday (27.07.25) and spoke of the pride she feels at playing for he country after coming up yet another big moment in an England shirt.
Kelly told BBC Sport: "I am so proud of this team. So grateful to wear this badge. So proud to be English.
"I was cool, I was composed. I knew I was going to hit the back of the net. I don't miss penalties twice.
"Unbelievable. All the staff behind us and Sarina Wiegman - she has done it again. Unbelievable.
"It is going to be crazy. I hope the whole of England comes out to support us and shows their love to these girls as they deserve it."
Kelly's place at the tournament had been in doubt after she was dropped by Wiegman earlier this year but praised the manager for giving her the chance to regain her place after she joined Arsenal from Manchester City.
She said of the coach: "She is bloody amazing. She is an incredible woman. What she has done for this country, we should all be so grateful for.
"What she has done for me, individually, she gave me hope, when I probably didn’t have any. She gave me an opportunity to represent my country again.
"I knew that I had to get game time, because representing England is never a given. But what she has done for the women’s game, not just in England, she has taken it to a whole other level.
"The work doesn’t go unnoticed from the staff that are behind her, they are incredible. people and I am so grateful to have worked with such amazing staff members."
