AceShowbiz - British singer Myleene Klass is pregnant with her second child. The former "Hear'Say" star announced the news to her Twitter.com followers, declaring: "Woo hoo! I'm pregnant! So happy!!"

She added, "Crikey, still reading all your msgs (messages). Bumps (sic) gona have a lot of aunts and uncles! X" The baby will be Klass' second with fiance Graham Quinn; they already share three-year-old daughter Ava.

Klass and Quinn have been engaged for five years and she recently postponed the wedding plan. "I told Gray I am tired of waiting and suggested a quick wedding in Vegas. But he replied, 'Just because you want to make it quick doesn't mean it has to be painful!' So we've hit stalemate again," she said.

But she also talked about having a large family, saying "Ava said to me the other day, 'I miss my sisters'. I said, 'Oh really? How many sisters do you have or do you want?'. She said she'd like two. I'd love her to have seven sisters. I don't think I could love anybody as much as I love Ava, but I have two siblings and I don't feel my mum loved any of us less."
