They dated on-and-off for close-to eight years - with marriage and engagement rumours regularly swirling.
However, Lewis Hamilton has now opened up about the real reasons why he and the always-gorgeous Nicole Scherzinger didn't ultimately go the distance.
And suffice to say that the former X Factor judge (she's due to return to the reality TV talent show later this year) mightn't be too pleased with his comments.
“My cars are my babies," the 30-year-old F1 star has now revealed in conversation with Top Gear magazine.
“I used to say, when I had a girlfriend, ‘I’m taking one of the girls out, so you can come if you want, but you come second when it comes to the cars.”
Ouch!
Nicole, 38, has previously hinted that Lewis had become “complacent” towards the end of their union, which first began back in 2007.
Last year, US chat show host Wendy Williams shocked the singer when she told her live on air that she had 'wasted' her best child-bearing years with Lewis.
"I was saying, truth, because you're 37, this is a woman who spent seven years of her life breaking up and getting back together," Wendy announced.
"Those are seven years you can never get back and he was really wealthy. I was rooting for you, girl. I'm sorry to hear about that."
