Nicole Scherzinger has revealed she wants to marry her racing driver boyfriend Lewis Hamilton.

The 33-year-old former Pussycat Doll singer has suggested that she would like the Formula 1 star to propose. Nicole also revealed that she is considering having a baby with Lewis.

Her desire to have children with the 27-year-old is said to have been the reason for their break-up last year. The two have been dating on and off since 2008.

"I would like to get married one day but it's not just up to me," she told British newspaper The Sun, adding having children with him "would be nice."

Last year, Nicole was forced to deny engagement rumours after her father spoke out claiming that she and Lewis were planning to wed.

Meanwhile, singer Miley Cyrus has fuelled rumours she is engaged to her actor boyfriend Liam Hemsworth after she posted a photograph of a diamond ring on her Twitter account.

The 19-year-old shared a picture of her manicured hand with what appeared to be an impressive engagement ring. She revealed the image alongside comments promoting nail care products.

"I am soooo obsessed with @jennahipp nail foundations! It looks so chic and classic! (sic)," she wrote.

Engagement speculation has been rife as Liam, 22, rises to fame off the back of the release of his new film The Hunger Games, which was a hit at the box office Friday.

The two have been dating since meeting on the set of their 2009 film The Last Song.

The couple last appeared at the Hollywood premiere of The Hunger Games where Miley said the hardest part about filming for Liam was "being away from me".
