Dannii Minogue's baby is due in July.
X Factor judge Dannii Minogue has announced she is expecting her first child with her boyfriend Kris Smith.
Simon Jones - a spokesman for the star - said the couple had received the results of her 12-week scan and were "delighted" by the news.
"Dannii and Kris are very excited and can't wait to start their family in 2010," Mr Jones said.
Minogue, the sister of pop star Kylie, posted on her Twitter page: "Woo hoo I'm gonna be a mummy."
Reports had recently suggested that Minogue had already had her 12 weeks scan, but Mr Jones denied that had been the case.
"Rumours and stories surfaced across the weekend about Dannii being pregnant and having already had her 12-week scan.
"These stories were incorrect. Dannii had her 12-week scan this week and was given the results today with the all-clear to make an announcement," he said.
The baby is due in July.
