Boxer Amir Khan and his wife Faryal Makhdoom Khan spent £100,000 on their daughter Lamaisah's second birthday party.
The celebrations for 250 guests took Mrs Khan three months to plan and included Disney princesses, Peppa Pig and a real-life ballerina.
The party, held at the home of Khan's beloved Bolton Wanderers football club, also featured a giant cake and a carousel.
During an exclusive interview with Hello! magazine, the 29-year-old talked about his daughter's big day.
"When I walked in, the first thing I said was, 'Wow!' My wife did an amazing job," Khan told the magazine.
"I was busy training when she was planning this, but every day I was getting crazy bills and thinking, 'What's this for?'
"Every penny spent on my daughter is worth it, though. After all, all this hard work I do is for her, for my kid."
Mrs Khan said: "I wanted it to be something really grand. Now I'm not doing anything until she's 16."
The 24-year-old from New York also revealed that she is happier after adjusting to the UK following the couple's wedding in 2013.
"I had a rough patch at the beginning when I got married to Amir," she said.
"But as I've lived with him, he's showed me a lot of things I didn't know about him.
"He is such a good guy, such a kind-hearted person. He's the type of guy that would give up things for his own happiness to make his wife and child happy."
She added: "Now we're at a stage in our marriage where we're the happiest ever."
Mrs Khan said parenthood has changed her sportsman husband and brought them closer together.
"I've never seen this side of him. He comes home early - before he used to be out with his friends. But now he's just like, 'My wife, my child and home'.
"I have to say to him, 'Can you please go out!' It's great for him and for us. He's changed, being a father, and I've changed being a mother. My life is all about my kid."
Khan has been involved in a number of aid ventures, including giving his time to help refugees.
The Bolton-born boxer plans to take up full-time work with his charity, the Amir Khan Foundation, when he retires from sport in a few years.
