The 33-year-old actress used sex as a “helpful” and “fun tool” whilst expecting her two oldest children – Luca, nine, whom she has with her ex Mike Comrie, and Banks, two, with her husband Matthew Koma – but has admitted she really wasn’t in the mood to get intimate with Matthew during her most recent pregnancy.

Hilary – who welcomed daughter Mae on March 24 – said: "Sex really was not interesting for me at all this time around. So toward the end, where with Banks that felt like a really helpful-slash-fun tool, this time I was like, 'Nope, not for me.' It annoyed me majorly when people would say, 'You know what really gets things started?' I'm like, 'Nope!'

“Poor Matt, but maybe not. Maybe he was like, 'This is for the better right now.'”

The ‘Younger’ star initially believed her reduced sex drive meant she was having a second baby boy, but now thinks it was just her body’s way of telling her she was “exhausted”.

She added: "I thought I was having a boy because with Banks I was totally down, and with this baby, I was like ... I don't know if it was maybe having more kids and trying to keep up with everybody that just made it kind of at night feeling exhausted and just really not a ton of time. I felt like a little more protective of my body this time around."

Hilary also recalled her time in labour with Mae, which lasted just three hours.

Speaking to People magazine, she said: "I was laughing at the way it was going down, because people were having to scramble to get home. I thought that was funny and I love to play tricks on people. There was humour in it and I felt really ready. Then it was probably about an hour and a half to two hours in, where they started to get super heavy and I was struggling to keep up. But my head was in the game and I felt a lot more confident in the way that I was birthing than I did before. So I was really trying to be present, and relaxed, and make every contraction work for me."
