Porn star turned sports presenter Mia Khalifa is undergoing surgery after her left boob was left “deflated” after being struck by a hockey puck.

The 25-year-old was watching a Capitals playoff game when the 6-ounce puck smashed into her chest.

And the Caps and West Ham fan has revealed she has to go under the knife at the start of next year to fix her breast.

The American-Lebanese babe told the Daily Star: “I was sitting behind the glass during a game, and it came shooting over the glass and it caught me so off guard and I had no idea it was coming.

“I grabbed my chest and I didn’t want to let go, because I felt like if I did let go blood was going to be everywhere.

“I got to take it home, it was the single greatest souvenir any hockey fan can get: a game-used puck that comes at you and hits you.

“They’re really heavy, it’s pure rubber, they go at about 80 mph. My left breast is slightly deflated now and I will be getting it fixed next year.”

However, Khalifa, who was once voted PornHub’s most-watched actress back in her adult entertainment heyday, insists the blow was not the most painful experience of her life.

She added: “I’ve seen my team [the Capitals) lose before, that’s a lot more painful.”

The Sportsball podcast co-host — who played hockey and lacrosse growing up in Washington — wrote to her 8.9 million Instagram followers after the incident: “I got hit in the boob with a puck during the game, and I’m 80% sure it ruptured an implant.

“But the good news is, I got a game used puck from a Capitals Stanley cup playoff game. Worth it.”

Khalifa launched Sportsball this month and says her show targets fans who “don’t take themselves too seriously.”

Earlier this summer, the beauty revealed how her love of West Ham transpired from across the Atlantic.

She said: “I watched ‘Green Street Hooligans’ when I was young and ever since then I’ve loved West Ham.

“I haven’t been to any games, that was actually my first time ever in England when I was there. I could see the stadium from where I was at the top of the tower, it looked a little far away.

“I would love to [attend a game], I actually plan on going back to do a food tour there. And I’m going to make it line up with a match that I can go and see.”

Khalifa added: “They [fans in ‘Green Street’] were just so rough around the edges and a little badass, and also I love the song, Bubbles.”
