The singer was spotted leaving the overseas clinic after completing treatment for alcohol abuse and depression, the Sunday Mirror reports.
"She's got herself together and she's ready to get back to some sort of normal life," a source said. "It's all about taking things easy, but she's hoping she's conquered her demons for good."
Harding will now focus on getting back together with Tom Crane, after calling off their wedding earlier this year.
A friend added "They've been in regular contact throughout her time away but only on the phone. They've spoken most days and it seems like they could have a chance of giving it another shot. She still loves Tommy, she's just not sure if things can get back to where they were."
A spokesman confirmed that Harding had left the treatment facility.
