Lewis Hamilton bought a puppy for Kim Kardashian's children and he loves "spending time with them".

The Formula 1 star has been dating the reality TV regular since earlier this year and he's now revealed he enjoys hanging out with the four children she shares with her ex-husband Kanye West - North, 13, Saint, 10, Chicago, eight, and Psalm, seven - and he expanded the family by buying the kids a Golden Retriever named Halo.

Speaking during a panel discussion at the F1 Grand Prix in Austin, Texas, Lewis shared: "My girlfriend's kids, I love spending time with them.

"She's got four, so I'm getting to play with these kids. I got them a dog this year, so little Halo is a new member of that family."

It comes after Kim admitted she's "really, really happy" in her new relationship.

She made the admission during a new episode of her reality show The Kardashians while speaking to comedian Nikki Glaser, 42, on the set of their upcoming film The Fifth Wheel.

Kim, who has been romantically linked to Lewis, 41, since February, discussed a list of more than 50 qualities she wanted in her ideal partner, before suggesting she had finally found someone who fulfilled them all.

When producers pressed her to reveal more about the mystery man, Kim said: "Oh, you guys are really trying to get this out of me."

She added: "Let me just say this, I am just really, really happy. That's all I'll say for now."

The comments came after months of speculation surrounding Kim's relationship with the seven-time Formula One world champion after their romance was first reported by The Sun newspaper in February.

According to the publication, the pair enjoyed a romantic getaway in the UK before their relationship became increasingly public, with the couple subsequently spotted kissing in Malibu, California, in April.

Kim, who divorced rapper Kanye West in 2022, has since become a familiar face at Formula One events, appearing at races to support the British driver.

During an interview with Sky Sports Formula One commentator Martin Brundle at the the Singapore Grand Prix earlier this month, Kim said of the sport: "I think (F1) is amazing and fun and wild, and something I've never seen before. It's amazing."
