Dannii Minogue has given birth to a baby boy, her spokesman confirmed today.
The 38-year-old X-Factor judge and her partner, Kris Smith, had a son named Ethan Edward Smith on Monday.
The couple were said to be "thrilled" with the new arrival.
Minogue's spokesman Simon Jones said: "Kris Smith and Dannii Minogue are thrilled to announce the arrival of Ethan Edward Smith on July 5 2010.
"Mother and baby are doing well and Dad is very proud. They request their privacy at this special time to adjust as new parents."
The baby boy is Minogue's first child and her spokesman confirmed that the baby was born in Melbourne.
The former Home And Away actress has said she had not considered starting a family until having the "right relationship" - with Smith.
She recently told the Mail On Sunday's You magazine: "I just never thought it was something I would do.
"I had never been broody. No clock was ticking. And I would never have wanted to do it unless I was in the right relationship. He felt like the one."
The singer's elder sister, Kylie, who has been busy promoting her new album Aphrodite, is reported to be flying over to welcome her new nephew in the near future.
Minogue's pregnancy has meant she has been forced to miss the recent X-Factor auditions, with stand-ins including Spice Girl Geri Halliwell and Pussycat Doll Nicole Scherzinger.
Shortly before giving birth, the star wrote on Twitter that she was pining to see the X-Factor judges.
She Tweeted: "Looking forward to catching up on XFactor auditions.
"Can't wait to see Simon, Cheryl and Louis again soon - miss them very much. Dx."Reuse content
