Kate Hudson's mom Goldie Hawn went for a swim and got pizza during her daughter's 18-hour labour with her son Bingham.

The 'Almost Famous' star is heavily pregnant with her first child, a little girl, with her actor boyfriend Danny Fujikawa, 32, and she has recalled the last time she was giving birth to her seven-year-old boy - whom she has with ex Matt Bellamy, with whom she also has 14-year-old Ryder - and how Goldie went off to exercise and consume snacks to kill time.

Appearing on 'The Ellen DeGeneres Show' on Thursday (20.09.18), Kate, 39, recalled: ''The best part was when mom called me when I was in labour and said, 'I'm was about to take a swim and then I was going to have a massage. How long do you think you're going to be labouring?'

''And I was like, 'I don't know, mom!' I'm like calling the nurse going, 'Do you know how long I'm going to be labouring? My mom wants to swim.'''

Goldie, 72, added of the tiring labour in 2011: ''I got hungry.

''She was in the stirrups and everything and was dilated. So I said, 'I'm really hungry, I'm just going to come back,' I came back with pizza and Doritos.''

Kate warned host Ellen that she could give birth at ''any second'' and also admitted she hasn't chosen a name for her new arrival yet, but they have a few in mind.

She laughed: ''Let's just say you've probably never had anyone this pregnant on your show. [My] water could go any second.''

And when asked if she or Danny have any ideas for a moniker for their little girl, she said: ''We have a couple of them and we're going to decide when the day comes.''

Kate announced her pregnancy with an adorable gender reveal video on her Instagram account in April.

She wrote: ''SURPRISE!!! If you've wondered why I've been so absent on my social channels it's because I have never been more sick! It was the most sick first trimester of all my children.

''We have been trying to keep this pregnancy under the radar for as long as possible but I'm a poppin now! And it's too darn challenging to hide, and frankly hiding is more exhausting then just coming out with it! My kids, Danny, myself and the entire family are crazy excited! A little girl on the way [sic]''
