Kelly Clarkson marked her daughter's third birthday with a princess-themed party.

The 'My Life Would Suck Without You' hitmaker and her husband Brandon Blackstock threw the bash for their daughter River Rose to mark the milestone birthday.

Sharing a collage of professional photographs taken at the event, Kelly wrote on Twitter: ''Happy Bday 2 our smart, witty & beautiful girl, River Rose! She wished 4 ''pink forever'' on her birthday (sic)''

River Rose wore a gold princess gown and even had her own little cast iron carriage, which was decorated with pink organza and flowers, whilst there was also a bright pink plastic one for riding round in.

And when it came to the cake, River Rose was treated to a giant yellow iced cake as well as an assortment of pink, blue and yellow cupcakes decorated with pictures of Disney characters.

Meanwhile, the 35-year-old singer - who also has 14-month-old son Remington Alexander with Brandon - previously admitted she has gained ''another level of confidence'' after having children.

She said: ''I've always been a confident person, I think that's just being Texan. But I think being a mom has brought another level of confidence, because basically the things a mom does daily - without adding a job - is pretty insane. We're gladiators, basically.''

And Kelly feels she is ''nailing'' it as a mother.

She added: ''I have never been more confident as a woman as I am as a mother. I feel like I am nailing it ...

''We have a blended family that is another level of trying to make it work and everyone feeling as equally loved and important. And then also just having a marriage and having a career and having everything. It is a lot.''
