The 38-year-old singer announced the news on his blog. "I've been keeping a secret from you all... me and Ayda are going to be a mummy and daddy this year... We had sex! It works!"
"We've seen scans and cried," he continued. "Looked at babies in commercials and teared up... the nursery is already planned... Basically I'm in love with a little person growing in mummy's belly... and can't wait to be a daddy... crying now."
This will be the first child for the couple, who wed in 2010.
