Christina Aguilera has revealed her new baby daughter's name.

The 'Genie In A Bottle' hitmaker - who also has a six-year-old son with her ex-husband Jordan Bratman - took to Twitter last night (17.08.14) to announce the name of her first child with her fiance Matt Rutler, after giving birth to her on Saturday (16.08.14).

She tweeted: ''So proud to welcome our beautiful daughter Summer Rain Rutler into the world.''

The 33-year-old singer - who was keen to have a natural delivery - is believed to have given birth by Caesarean section.

A source previously said:''She's due at any moment. But she's freaking out because with her first child, Max, she had a C-section. This time, though, she wants to have a natural childbirth.''

Meanwhile, the pretty blonde recently showed off her baby bump in V magazine saying she felt ''proud'' of her figure through every stage of life.

She said: ''As a woman, I'm proud to embrace my body through all stages of life, staying fearless and confident in surrendering to the unknowns the future has in store.''
