Lake Bell has given birth to a baby girl.

The 35-year-old star first sparked rumours she was pregnant in April when she stepped out on the red carpet at the Vanity Fair party at the Tribeca Film Festival in New York City wearing a tight-fitted jumpsuit, which clung to her blossoming baby bump.

However, the brunette beauty didn't appear to be in a rush to get everything ready for the arrival of her baby as she took to her Instagram account last month to post a photograph of the tiny tot's messy nursery.

Alongside the snap, which sees Blake holding a new paintbrush and wearing a white safety mask, she wrote the comment: "Everything is ready to go! Sterile, chillaxing, serene....Hope baby comes early!

#hopebabyunderstandssarcasim (sic)."

Meanwhile, Lake previously revealed that she was struggling with her pregnancy because her sense of style had taken a sudden turn as she needed to accommodate her baby bump with supportive clothing.

She said in August: "It's less enjoyable right now. I'm seven months pregnant and my style sense is a little off! At the moment, I'm just aiming to keep my sanity and continue to feel as chic as one can. I have to straddle a line of being tasteful and looking good; I need a shape that looks elegant and is supportive without being too hot: it's a daily negotiation!"
