Update (March 17, 2014):

As we still wait to hear from Nicole herself, Us Weekly reports the pop singer is actually not engaged to her on-again, off-again boyfriend.

"He hasn't proposed," the unidentified source tells the magazine. "They only just got back together at Christmas, so it's very much at a point of working things out still." But we just want a wedding!

Original story (March 16, 2014):

Don't cha love it when things end happily ever after? Pussycat Dolls star and former X Factor judge Nicole Scherzinger is reportedly engaged to longtime boyfriend Lewis Hamilton.

British race car driver Lewis, 29, recently proposed to Nicole, 35, after five years of dating on-and-off, according to the Daily Star. The couple began their relationship way back in November 2007.

As we had previously reported, the couple parted ways in the summer of 2013, using the classic "busy schedules" excuse. They had also split up back in 2011. But they apparently rekindled things in late 2013.

Lewis reportedly popped the question last month, and Nicole said no, so he tried again this month, and she finally said yes. This is reportedly the fourth (!) time he had proposed to her. If at first you don't succeed... 

"He got down on one knee, and Nicole finally accepted," says a source. "The plan is, they are going to live together in Switzerland and travel together when Lewis is racing."

"Lewis is doing his best to keep the news ­under wraps, but he is ­absolutely delighted," the insider adds. "Of course, this means her career will have to take a back seat for a while, but she is ready to support him on the track."

This is certainly an exciting time for Nicole, who was a judge on the X Factor in Season 1 and on X Factor UK in Seasons 9 and 10. She recently signed a record deal with Sony to produce her second solo album.

We wish the happy couple all the best!
