Now, Simon Cowell is ready to unveil her to the American public. Cole will join her boss and music mogul Antonio 'L.A.' Reid on the judging panel for The X Factor USA.
As her name trends worldwide on Twitter, we're wondering how many people across the US are sitting, scratching their heads asking, 'Who?!' Fear not, we're here to help!
Who is she?
Born Cheryl Ann Tweedy on June 30, 1983, she was the fourth of five children for Joan and Gary Tweedy. Her early interest in sequence dancing led her to join The Royal Ballet aged 9. As a child she appeared in various advertising campaigns and won various modelling competitions. After leaving school at 16, Cheryl took on various jobs including working as a waitress in a restaurant. In 2002, she auditioned for a new UK reality TV show called Popstars: The Rivals.
Cheryl first met her future X Factor UK colleague Louis Walsh when she auditioned in front of him, Spice Girl Geri Halliwell and Pete Waterman for the talent show. The plucky teenager progressed to the live shows and competed on a weekly basis to secure a place in a girl group. She eventually formed Girls Aloud with Nadine Coyle, Sarah Harding, Nicola Roberts and Kimberley Walsh. The fivesome shot to number one in the UK with their debut single 'Sound of the Underground'. However, drama was just around the corner for Cheryl.
The toilet attendant incident
On January 11, 2003, Cole was involved in an altercation with Sophie Amogbokpa, a nightclub toilet attendant. A subsequent trial saw Cheryl found guilty of assault occasioning actual bodily harm, but cleared her of racially aggravated assault. The popstar was sentenced to 120 hours of community service and ordered to pay prosecution costs as well as compensation to Amogbokpa. Speaking last year, Cole insisted that she does "regret" the incident, but insisted that she had acted in defence. Back in 2003, once the drama died down, it was back to the music...
Girls Aloud were unstoppable. Following their debut number one single, they went on to score 20 consecutive top 10 UK singles - four of which have hit the number one spot. The fivesome subsequently hold the Guinness World Record for "Most Consecutive Top Ten Entries in the UK by a Female Group". With five albums to their name and a series of sold out arena tours, Girls Aloud confirmed that they were taking a break to pursue solo projects in 2009. The group's manager has confirmed that they will reunite to celebrate their 10th anniversary next year. Although with Cole's new job, it's not clear if those plans will ever come together.
Cheryl quickly became a British tabloid favourite. In 2004, she began dating English footballer Ashley Cole. Their romance blossomed and the couple married in 2006. Following claims of betrayal in 2008, Cheryl stood by her husband and took to Twitter to show that she continued to wear her wedding ring. However, following further allegations against Ashley, Cheryl confirmed that she had separated from her husband last February. She filed for divorce in May 2010 citing "unreasonable behaviour". In an interview, Cheryl confirmed that she was continuing to use her married name because changing back to Tweedy would suggest that she was "ashamed" of her four-year marriage. Rumors surrounding her love life continue with various tabloids and magazines continuing to speculate and link her to both will.i.am and close friend Derek Hough.
Cole first ventured outside of Girls Aloud in 2008 when she featured on will.i.am's 'Heartbreaker'. In October 2009 she released her debut solo album 3 Words. The album and lead single 'Fight For This Love' both topped the UK charts. Future releases including the LP's title track and single 'Parachute' went on to secure top five positions. Cole repeated her success with sophomore album Messy Little Raindrops. To date, the collection has spawned number one single 'Promise This' and top 40 hit 'The Flood'. It was recently confirmed that will.i.am is managing Cole as she launches her US career.
While the latest Young Music Millionaires list put her estimated worth at £12m ($19.7m), Cole continues to do her bit for charity. In 2009, she was one of ten celebrities who climbed Mount Kilimanjaro in aid of Comic Relief. The epic challenge raised over £3.4m ($5.6m). Earlier this year, she confirmed the launch of The The Cheryl Cole Foundation in aid of The Prince's Trust. Cole met with Prince Charles to launch the Foundation, which will raise money to continue helping disadvantaged young people from the North East of England.
On June 10, 2008 it was confirmed that Cheryl Cole would replace Sharon Osbourne on The X Factor UK. At the time, the 24-year-old said it was "scary" but a "massive honour" to join the show. Cole quickly settled into the job and in her first year mentored Alexandra Burke to victory. She went on to repeat her success the following year as Newcastle singer Joe McElderry sung his way to victory. Fellow judge Dannii Minogue prevented her from scoring a hat-trick last year, as Matt Cardle pipped Cole's Rebecca Ferguson in the series final. With her trademark Newcastle slang, it's going to be interesting to see how America takes to Cole's critique, but one thing is for certain - she is determined to become the first winning X Factor USA judge.
