Heaton in hospital for heart problems

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

The singer, who is being treated at hospital in Watford, has kept up a steady stream of comments on Twitter during her stay.

Writing on the micro-blogging site today, she said: “I am having a small operation to fit a 3 year heart recorder this afternoon It’s scary but so …

“…grateful to #watfordgeneral #nhs 4looking after me & deciding this is best course of action. I’m sure the operation will b fine.”

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

Bit of a rough night. Not nice hearing the cries of other patients in the ward .. It brings on your own sadness.. Hopefully discharged later
