The 32-year-old actress has become a mother for the second time as she took to Instagram on Saturday (15.10.16) to share the news of Daisy Josephine Sudeikis' birth.

She captioned a photo of her daughter: "There goes the neighborhood. Daisy Josephine Sudeikis. Born, like a boss, on #internationaldayofthegirl. (sic)"

The 'Tron: Legacy' star and her 41-year-old husband - whom she married in 2011 - are already parents to two-year-old son Otis Alexander, and the beauty previously admitted the pair used metaphors from 'The Angry Birds Movie' to explain her pregnancy to their tot.

She said: "He knows that it's something in an egg. We just used metaphors in ['The Angry Birds Movie' to explain it to him]. That's all. We explain everything through the movie."

The news of Daisy's birth comes after the 'Vinyl' star recently complained on Twitter when she was left to stand and sweat on a hot and cramped underground train for the duration of her public transport journey as not one person offered to give up their seat for her.

Courtesy guidelines printed inside the subway cars clearly state that able bodied passengers should offer their seats to elderly, disabled, or pregnant travellers, as they are less likely to be able to stand during their trip.

The star wrote on the social media website: "NBD, able-bodied [subway] riders who won't give your seat to a GIANT preggo. I'll just stand riiiiight next to your head and pray I go into labor (sic)"
