Kelly Clarkson has given birth to a baby girl.

The 32-year-old singer and her music manager husband Brandon Blackstock welcomed River Rose, their first child together, into the world on Thursday (12.06.14).

The 'Stronger' hitmaker took to her Twitter account today (14.06.14) to announce the happy news, tweeting: ''Our baby girl River Rose Blackstock arrived on June 12th! Thank you everyone for all of your well wishes! Brandon and I are on cloud 9!! (sic).''

The blonde beauty, who announced she was expecting a daughter earlier this year, had a difficult pregnancy early on after battling with morning sickness.

She tweeted at the time: ''Ladies if you r pregnant & sick as a dog trust me when I say the one thing u will keep down might just be ''baked potatoes'' #godblesspotatoes (sic)''

Meanwhile, the 'Breakaway' singer wanted to have a happy baby and even made it her wish for her 32nd birthday.

She wrote on April 24: ''It's my birthday!!!! For my birthday I have asked my unborn baby girl to sleep through the night and laugh a lot when she comes out :) (sic)''.

Kelly married Brandon, who has two children from his first marriage, Seth, seven, and Savannah, 11, in a low-key ceremony in Tennessee last October, and shortly afterwards admitted she couldn't wait to fall pregnant.
