Sarah Harding is still "struggling" with her knee after suffering an injury while taking part in Channel 4´s The Jump in February.
The former Girls Aloud star was one of the celebrities forced to pull out of the winter sports reality programme due to a ruptured ligament.
Nearly six months on, Sarah, 34, said she still has "another month of physio" to go.
She said during an appearance on This Morning: "I'm still struggling with my knee ... I can't go to the gym as much as I used to."
The singer told the ITV programme hosts James Martin and Anita Rani: "I'm walking again. I was literally in a knee brace for quite some time. I couldn't go to the gym but I'm gradually getting back into toning up."
The Jump came under scrutiny this year as a number of contestants were left with injuries.
Former Olympic gymnast Beth Tweddle was involved in a horrific crash that left her needing surgery on her spine.
The 31-year-old sports star had part of her hip removed to fuse two fractured vertebrae in her neck after she crashed into a barrier when landing a jump on the show.
Former Olympic champion swimmer Rebecca Adlington, 27, also withdrew from the show on medical advice after a shoulder injury.
Holby City actress Tina Hobley, Made In Chelsea's Mark-Francis Vandelli and Olympic gold medal winner Linford Christie were among the other participants who were injured while taking part in the programme.
Sarah is currently preparing to take on a leading role in Ghost: The Musical, a stage version of the 1990 film, which starred Demi Moore and Patrick Swayze.
