1. Kelly was born Kelendria Trene Rowland on February 11, 1981 in Atlanta, Georgia to mum Doris Rowland Garrison and dad Christopher Lovett.
2. In 1991, she joined friends Beyoncé Knowles, LaTavia Roberson and others in rapping/singing/dancing ensemble Girl's Tyme (ugh!). In true girl-group tradition, a number of lineup changes took place as the girls tried on loads of new names for style - including Something Fresh, Cliché, the Dolls and Destiny. Inspired by a passage in the Book of Isaiah, the group were finally rechristened Destiny's Child by Beyoncé's dad Mathew and mum Tina.

3. Kelly moved in to the Knowles household in 1995 when Matthew gave up his salesman job to concentrate on managing the band. When they were still plain Destiny, the group were signed to Elektra, but they were dropped before they could release any material. Picked up by Columbia in 1997, they eventually became one of the biggest girlbands of all time.
4. Destiny's Child recorded four proper studio LPs, a Christmas album and a clutch of chart-topping singles. They sold more than 60 million records, won loads of awards and survived through lineup changes, lawsuits and the rest before calling it a day in 2005 after their 'Destiny Fulfilled... And Lovin' It' world tour. Rowland and Beyoncé were the only two who stayed the whole course - though mini-Knowles Solange filled in on stage for Kelly in 2000 when she broke a couple of toes.

5. While DC were on a break in 2002 Kelly released her first solo album Simply Deep. After the split, she followed her debut with Ms. Kelly in 2007 - and will finally release her third record Here I Am later this year, on the crest of an X Factor wave. I think we've found a new artist to take over the annual Cheryl Cole Performance Slot™!
6. Kelly has also spread her wings outside of music, having a guest spot on sitcom The Hughleys in 2002 before winning parts in Eve, Girlfriends and American Dreams. She made it to the big screen in 2003 in slasher flick Freddy vs. Jason. In the movie, Freddy and Kelly's character Kia trade offensive slurs ("dark meat"... "f*ggot") for a while, before Jason cuts their conversation short.
7. Like the critics, Kelly was not mad about that film, it seems. "One of my friends wanted to watch it on the weekend and I was like, 'NO!' She'll probably bring it round and make me watch it anyway. So we'll see," she told Popjustice a few years back. She also admitted to not being a fan of Destiny Child's 'Bugaboo'. "Some of the stuff in that song makes me feel like I'm 17 years old, especially the line 'So what? You bought a pair of shoes' - it's such a bad line to have to sing in concert. 'You bought a pair of shoes'? What terrible lyrics."
8. While most of her contemporaries fall over themselves to squeal that no, they've not had any surgery, Kelly isn't at all embarrassed at having some cosmetic tweaks. After a decade of holding back, she had her breasts enlarged in 2007 and suggested that it was like getting your teeth cleaned. More recently, she said that she isn't averse to further work. "If my butt is falling I'm going to pick it up." Botox, however, is off the menu. "I don't want needles stuck in my face, that's going to hurt!" Having seen a boob job on the telly once I can't imagine Botox stings any more than that!
9. Talking of boobs and the like, Kelly admitted that her hit single 'Work' "means exactly what you think it means". ("Put it in... You was talking tough up on in the telephone/ So you better put it in when we get it on... Use both hands to make sure I reach my destination")...."I remember when the writer was writing it and he was like, 'Put it in, put it in', and I said, 'This is a nasty record'."

10. The X Factor isn't Kelly's first experience of reality talent contests. As well as that pre-teen spot on Star Search she also co-hosted Bravo's The Fashion Show for one season before being replaced by supermodel (and wife of David Bowie) Iman. Those wanting a hint on her judging style should note that she sees Cheryl Cole as her panel role model. Asked how she would approach the show, she said: "It would definitely be constructive. That's what I really like about watching Cheryl Cole. I feel like she's very constructive as a judge."
