Yael Stone has given birth to a baby girl.

The 'Orange is the New Black' actress and her partner Jack Manning Bancroft welcomed their first child into the world last month, her representative has confirmed.

The couple are already experiencing sleepless nights with their daughter, who has been named Pemau, but are ''very much in love'' with the tot.

Yael's spokesperson confirmed to US Weekly magazine: ''On May 30th Pemau Stone Bancroft was born to Yael Stone and Jack Manning Bancroft.

''Her mum and dad are very tired and very much in love.

''She was named after her great great great grandmother who provides a powerful link to the past, the Bancroft's oldest link to the Djanbun clan of the Bunjalung nation.''

Just a few weeks ago, the 33-year-old star shared a picture of her bare bump as she hailed the final stint of her ''incredible journey''.

She wrote on Instagram: ''Moving into the final stages of this incredible journey with respect and gratitude for the women who have come before me.''

The Australian actress has shared a number of photos of her changing shape on her Instagram account throughout her pregnancy and even used her bump to spread messages.

In March, she showed her support for the March For Our Lives anti-gun violence demonstrations by writing 'Don't Shoot!' on her bare stomach and captioned the picture: ''Standing in Solidarity with student led action in the USA to end gun violence. Respect for human life over dollar$ #marchforourlives (sic)''

Yael was previously married to Australian actor Dan Spielman, who she wed in 2012. But in 2017, she revealed their relationship had been over for a year.
