The former TOWIE star, 27, took to social media to share the news that his girlfriend Holli Willis is expecting a little girl.

Sharing a snap of the scan, Kirk gushed: "Everyone meet mine and @xhollixwillisx little girl!!!! Proudest moment of my life so far!!!! [sic]."

Kirk and Holli have been dating since earlier this year, but he revealed in April that they first got together when he was 20.

Speaking to Now! magazine, Kirk said: "When I got back from filming [Ex on the Beach] I bumped into Holli Willis, who I used to see when I was 20, and we hooked up straight away.

"It's going great. I'm madly in love. She's got a little four-year-old daughter and it's like I have a ready-made family. It's great."

Kirk also confirmed that's he's 'done' with reality TV, adding that he just wants to settle down with Holli.

It looks like Kirk has been getting in a lot of daddy practice with Holli's little girl.

This week he shared a snap of the two of them on Instagram, writing: "Got little Scarlett in bed with us this evening!!!!!! She's better on the iPad than I am! #familyfirst [sic]."

Kirk's happy news comes after it was confirmed his former The Only Way Is Essex co-star Sam Faiers is expecting her first child with boyfriend Paul Knightley.

Congratulations to Kirk and Holli on their happy news!
