The former Pussycat Doll, 35, is said to have accepted Lewis' proposal after their recent reunion.
According to today's Daily Star Sunday (16 March), Nicole has finally said yes after allegedly turning Lewis down on three previous occasions!
A source told the newspaper that the driving ace popped the question at his Swiss mansion where the pair will set up home together after marrying in August.
They say: "Lewis is doing his best to keep the news under wraps but he is absolutely delighted.
"He got down on one knee and Nicole finally accepted."
Last week, Lewis described singer Nicole as his "wifey" after posting a shot of the pair at the Sistine Chapel in the Vatican City.
The former X Factor judge and the British Formula 1 star have been on-off for five years, as the long distance nature of their relationship has taken its toll. They got back together last year.
Lewis, 29, is currently in pole position for today's Australian Grand Prix.
If the news is true, we'd love to congratulate one of our favourite showbiz couples!
