CELEBRITY WEIGHT LOSS Slim Sarah Harding displays her abs in crop top
Sarah Harding looked super-thin today as she headed out in her gym gear.
The Girls Aloud star, who was eating an apple, displayed rock hard abs in a cropped Run DMC top, which she teamed with black leggings and trainers.
Sarah, 30, glammed up her outfit with a pair of sunglasses, sleek hair and a full face of make-up.
The singer had a tough end to 2011 - she went to rehab in South Africa in October to deal with her alcohol dependency and addiction to Zopiclone tablets.
Sarah, who said her drinking spiralled out of control after her split from fiancé Tom Crane, spent her first 3 days in the clinic in detox, where she was put on valium.
'They literally comatose you in case you have a fit,' Sarah told The Sun.
'Because if you come off alcohol too quickly you have fits.
'I wasn't drinking as heavily as some people in there, so luckily I got out after 3 days to continue my treatment.
'Everything was OK with my body, my liver was OK.
'I had all that checked.'
