When you're nearing the end of your incredible nine-month journey, it can be super-difficult to remember your pre-pregnancy life - a sensation which can make you feel like you've been sporting a baby bump forever.
One celebrity mum who knows all too well how long a pregnancy can feel is Liv Tyler who, on account of having her youngest children in very close succession, struggles to remember a time when she wasn't expecting.
The Armageddon star, who first became a mum in December 2004, had her second child - a son named Sailor Gene - in February 2015 before announcing she was pregnant again shortly after Sailor's arrival last year.
The actress, who is engaged to sports and entertainment manager David Gardner, opened up during a recent interview with The Times and explained that the brief period between her second child's arrival and her third's conception can make her feel like she's "been pregnant forever."
In remarks which are bound to resonate with any mum who has children very close in age, Liv, who was once married to British musician Royston Langdon, explained: "I have been pregnant for two years straight. It feels like forever."
While Liv, whose partner David is the proud father of a little boy named Gray from a previous relationship, admits she once loved the prospect of having a big family, she reveals that she's unlikely to have any more.
"I think we will be done after this. It's funny because I always knew when I was a little girl that I wanted to have children and I always envisioned having a little tribe," she explained while reflecting on the impact her new and impending arrivals have had on her and her fiancé.
Liv, who will turn 39 this summer, announced her third pregnancy last month.
