Katherine Jenkins is pregnant with her second child.

The 37-year-old soprano has announced that she and her husband Andrew Levitas - who she married in 2014 - are expecting a little brother for their two-year-old daughter Aaliyah Reign and the tiny tot is due to be born sometime next year.

Taking to her Twitter account this morning (14.11.17), the blonde beauty uploaded a photograph of Aaliyah with her back to the camera wearing a pink cape with the words, ''Sidekick coming soon...'' embedded into the sweet shot.

Katherine added: ''Andrew and I are overjoyed that our family will be growing in 2018 with the addition of our second child - a baby brother for our little superhero Aaliyah!!!''

The news that the couple are adding to their brood comes just months after the Katherine said she'd love to have another baby but they weren't planning anything.

She said: ''We definitely want another child. There's no ovulation charts on the wall or anything ... not yet anyway ... but that's because I'm about to go on tour. But we hope we will be lucky enough to have a second child.''

Katherine married Andrew within a year of meeting him but she has admitted they moved so fast because she was so sure about her future with her beau.

She said: ''It has been a whirlwind. I'm not a person who rushes into anything. I consider things and I'm actually quite cautious, especially with big decisions. But when you know, you know and with Andrew, I just knew straight away. He's an amazing husband, an amazing dad and I just feel like I understand the reason for everything now.''
