Khloe Kardashian has revealed the name of her baby girl – True Thompson.

The 33-year-old Keeping Up With The Kardashians star gave birth to True last Thursday in Cleveland, Ohio.

Taking to Twitter and Instagram on Monday, Khloe posted an image of a room filled with pink balloons and flowers saying she and True's father Tristan Thompson are "overwhelmed" with love for their daughter.

"Our little girl, True Thompson, has completely stolen our hearts and we are overwhelmed with LOVE," said the message.

"Such a blessing to welcome this angel into the family!

"Mommy and Daddy loooooove you True!"

Kardashian did not publicly confirm she was expecting until she was almost six months pregnant.

She eventually shared a photo of her baby bump on Instagram, saying it was her "greatest dream realised".

The baby is the third for the Kardashians and the Jenners this year.

Kylie Jenner welcomed her first child, Stormi, in February, and Kim Kardashian West and husband Kanye West had their third child, Chicago, via a surrogate in January.
