She's got the voice, the looks AND grooves.
But now it appears that Alexandra Burke has got her fabulous curves back. And she's not afraid to use them.
The former X Factor winner was on fine form last night as she notched up another stellar performance in Southend on the latest leg of her All Night Long tour.
Muscular: Following her dramatic weight loss after winning the X Factor, singer Alex Burke has regained some of her womanly curves and was not afraid to flaunt them on stage in Southend last night
Shake that booty! It looks as though Alex has been taking a few dancing tips from her icon Beyonce as she struts her stuff on stage
But the 22-year-old has certainly come a long way since her 2008 victory on the hit talent show.
Back then, the singer was known for turning out consistently excellent performances, but was often critisiced for her sometimes wooden appearance on stage.
She was also famed for her penchant for long, ball-length gowns which hid her killer curves which she subsequently lost.
Fast-forward to 2011, and it's clear that Alexandra has been working on her stage presence as well as regaining her womanly curves and has been wowing fans with a series of extremely raunchy dance routines.
It's a cover-up: Alexandra appeared to be a lot more demure during the X Factor final in 2008 when she wore a stunning gold dress
Get down to it: The former X Factor winner's career has gone from strength to strength in the last year notching up a number one single and embarking on her All Night Long tour of the UK
Athletic: The singer's energetic routines on her UK tour have left her with a body more like an athlete
She appeared more than happy to flaunt her newly honed body which she showcased in a number of jaw-dropping skimpy, if somewhat unflattering, outfits which have been created especially for her by designer Melissa Odabash.
The singer made a number of outfit changes during her set none of which left much to the imagination.
In fact, she appeared to be channelling her icon Beyonce in a number of figure-hugging leotards which highlighted her muscular physique.
Following her energetic performance last night, she tweeted: 'Southend !!! Thank you all sooo much!! Sorry I couldn't stop and sign autographs - we had to make a quick dash back2london.'
Unflattering: The 22-year-old's womanly physique was not shown at their best in this unflattering silver leotard
Racy lady: Since winner the X Factor, Alexandra Burke's on-stage outfits have become increasingly skimpy whilst her dance routines appear raunchier than ever
Energetic: The singer looks toned and healthy as she performs a raunchy routine in Southend
London-born Alexandra, who performs some of her biggest hits on the tour including Bad Boys, Broken Heels, Hallelujah and Start Without You, as well as her new single The Silence, took to Twitter again today as she prepares for the final performance of her tour in Ipswich tonight.
But it looks as though Alexandra will be keeping herself busy once her tour is over.
She said recently: 'I want to oversee my business, my brand. If I want to be here for the next 50 years I have to make sure this is a good little business.
'I want to make myself a brand, and make sure when I go out there what you're seeing is a brand, someone who cares about their music and creativity.'
