Demi Lovato has been given a big boost in her post-rehab comeback - the heartfelt song she struggled to record during her lowest period last year (10) has rocketed into the top 10.
The teenager admits Skyscraper brought her to tears when she first tried to record it, because the song appeared to detail her secret struggles with depression and eating disorders.
After spending three months in rehab at the end of 2010 and the beginning of 2011, Lovato returned to the studio and recorded the song as an anthem to fans who were struggling with problems - and now the track's a big hit, debuting at number 10 in the new Billboard Hot 100 countdown.
LMFAO still rule the chart with Party Rock Anthem, claiming a third week at number one and Pitbull stays put at two for a third consecutive week with Give Me Everything.
Katy Perry's Last Friday Night (T.G.I.F.), Adele's Rolling in the Deep and Super Bass by Nicki Minaj round out the new top five.
