Pink has been put on ''vocal rest'' after being forced to cancel two concerts this week.

The 'True Love' hitmaker has thanked fans for their well-wishes after two US shows were postponed due to illness - and she joked there wouldn't be a problem if she ''lip synced.''

She wrote on Twitter: ''Thanks for all the support y'all. Not very dramatic- doctor just wants me on complete vocal rest for four days to heal. So I can kick ass.

''Both shows rescheduled and very quickly. Touring would be terribly easy if I lip synced. See you soon xo. (sic)''

She is currently in the US for the Truth Above Love tour, and tonight's show in Salt Lake City has been cancelled along with tomorrow's concert in Denver - they have rescheduled to October 29 and 30 respectively.

Pink - who has a two-year-old daughter Willow with husband Carey Hart - recently spoke about her training regime and how despite indulging in her favourite food, she still managed to work hard and regain her pre-pregnancy body.

She previously said: ''I train five days a week for an hour and a half, plus rehearsals if I'm touring - but I eat a lot too. I like food and I like my wine, so I don't let it stop me from enjoying myself.''
