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 last Thursday (12.06.14).

The 'Stronger' hitmaker took to her Twitter account over the weekend 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 and found potatoes helped settle her stomach.

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, Kelly - who is a stepmother to Brandon's children Savannah, 12, and Seth, eight - was delighted when she discovered she was pregnant since the couple only had been trying to conceive since their wedding in October.

She said last autumn: ''[We want a baby] now! Practice makes perfect! We're trying, trying, trying ... Like rabbits!''
