Former singer and reality television star Michelle Heaton is being treated in hospital in England, and has kept up a steady stream of comments on Twitter during her stay.

The former Liberty X star is having a “small operation” to fit a heart recorder after she was taken ill last week.

The singer is at a hospital in Watford and is staying in touch with fans during her stay through the micro-blogging website.

The mother-of-one wrote, “I'm having a small operation to fit a 3 year heart recorder this afternoon. It's scary but so grateful to #watfordgeneral #nhs for looking after me and deciding this is the best course of action. I'm the sure the operation will be fine.”

Last week, Heaton told her fans; “As you may or may not know, I have suffered from long and scary heart problems over the years.”

Michelle, who was previously married to singer Andy Scott-Lee, married an Irishman, Hugh Hanley, in 2010 and gave birth to their daughter in January. The 32-year-old, who put on 3 stone when she was pregnant, gave birth to her daughter, Faith, by emergency caesarean section.

Michelle was advised by doctors to wait at least six weeks before she started exercising again. She waited a further two weeks before starting her new regime.

In June she tweeted to fans that she thought her pregnancy weight would fall off straight after birth. She admitted she was wrong but said she had finally reached her goal weight again.
