Michelle Heaton - Michelle Heaton Is Pregnant

The Liberty X singer, who turns 32 on Tuesday (19Jul11), and her husband, Hugh Hanley, are expecting a baby in early 2012.

She tells Britain's OK! magazine, "I can't believe this is happening at last! In six months our lives are going to change forever!"

However, Heaton, who was previously married to singer Andy Scott-Lee, is anxious about the birth because she suffers from an irregular heartbeat.

She adds, "It means I'm a high-risk pregnancy, which is a bit of a worry. So far I've had two heart blocks where I almost passed out, and I get palpitations almost every day. I'm worried about how giving birth is going to affect it all."
