The 24-year-old daughter of TV chef Gordon Ramsay revealed the news in a social media post.

"I am marrying my best friend," she wrote on Instagram, alongside photos of the pair and the engagement ring on her finger.

"I truly cannot put into words how I am feeling right now... Thank you for letting the little girl inside of me feel loved, seen and happier than ever. I love you & I cannot wait to be your wife."

She added that she will "always be there" for former Strictly Come Dancing star Peaty, and his son George.

"Everything is better with you. Everything has been better since you. Here's to forever," she added.

Peaty said he was the "luckiest man on earth" as he also later posted about the engagement on his Instagram page.

"I can't believe you're going to be my wife," he wrote.

"I'm truly the luckiest man on earth to have such a gentle, caring and beautiful woman by my side. You fill my heart to the brim and give my soul peace."

He said Ramsay had been with him "at my lowest and helped me understand myself to navigate my own darkness".

"You have also celebrated the highs which have been so many, as for the first time in my life, I'm happy with the man I've become," he said.

"You came to church with me and joined the incredible community we have there without a question."

The 29-year-old athlete added: "Seeing you show the love you give to the most important person in my life, George, even from day one, there was never a question about you becoming my wife one day.

"I'm looking forward to our life together and the many challenges we'll face. I promise to always love you with all my heart."

Ramsay and Peaty also quoted passages from the Bible, with the swimmer also revealing in an additional Instagram story post that he had been working with a jeweller for 10 months on the ring.

Peaty, who missed the 2022 World Aquatics Championships after breaking his foot in a freak training accident, previously admitted going on a "self-destructive spiral" after the 2022 Commonwealth Games, which led to him taking a break from the pool.

The three-time Olympic gold medallist won silver at this summer's Paris games.

He separated from his girlfriend of three years - and the mother of his son - in August 2022.

The former Strictly star competed in the 19th series of the BBC One dance show in 2021 and reached week seven, finishing ninth with his professional partner Katya Jones.

Ramsay's sister Tilly, who was a contestant the same year as Peaty and was partnered with Nikita Kuzmin, was among the first to congratulate the couple in the comments section of her sibling's post.

"Couldn't be happier for you both!! I love you guys," she wrote.
