Lewis Hamilton "feels pressure" to marry Nicole Scherzinger.
The 29-year-old Formula One racing driver - who dated the former Pussycat Dolls singer on/off since 2007 before making their relationship official in 2013 - has revealed that her family is keen for him to pop the question.
He said: "I'm certainly feeling pressure, heat from family members.
"But Nicole's massively focused on her work the same as I am. We're happy just way we are. [Marriage at] one point...will be for us."
Lewis also revealed that the couple have simple plans for their Christmas presents for each other.
He told E! News: "I was just in the car thinking, what do I get her? It's not like we've not got everything we ever wanted.
"We did discuss that this Christmas we'd do something fun, such as having a set fee - $10 each - and you gotta go and buy as many or as little cool things, fun things, silly stuff.
"So maybe we'll do that. We don't need anything else. We got everything we've ever wanted."
Meanwhile, Lewis recently revealed that the pair were too "young" to have children.
Speaking about the future of his relationship with Nicole, he said: "She's amazing with kids, I think we're both pretty good with kids ... but we don't have time for that at the moment.
"There are so many things we want to do, but the great thing is that we support each other with it. All in good time. She's still massively young and I'm still young man!"
