Anne Hathaway has finally confirmed that she and her husband did in fact plan what she referred to as her 'buzzer beater' pregnancy.

The 43-year-old has been proudly showing off her blossoming baby bump as she whirls through the publicity rounds for Christopher Nolan's The Odyssey.

She and her husband Adam Shulman, whom she married in 2012, were already parents to two sons - Jonathan, ten, and Jack, six.

Fans were left in awe when she announced last month that she was expecting her third child, noting her age at the time of conception.

Now Hathaway has expressed her own astonishment at the 'amazing' development, in an interview this Monday on Late Night with Seth Meyers.

'I mean, we knew what we were doing, but we were so shocked it worked!' she said. 'We knew, and yeah, but no, we were just - we were so shocked it went this way.'

The Daily Mail has contacted a representative for Hathaway for comment. 

Hathaway went public with her pregnancy with an Instagram video of herself hugging her growing belly, set to the song Baby, I'm Yours by Barbara Lewis.

She had remarked on how 'lucky' she felt to be a mother this April, in an interview accompanying her coronation as 'Most Beautiful Woman' by People.

'I know that not everybody who wants to be a parent gets to be,' the The Princess Diaries actress observed. 'I’m just blown away by how fortunate I am. It went really well for me twice, and that’s really lucky.'

Hathaway raved that her husband 'supports me completely', adding: 'I’m so lucky that he’s my partner that I spend my life with.'

She added: 'If I didn’t know that before this past year, I think I really know it now because with absolutely everything he’s just, he’s on it. He holds it down. I hope that doesn’t sound like I’m bragging, but he’s a dream partner to me.'

Hathaway has experienced a banner year professionally, including the release of her smash hit movie The Devil Wears Prada 2 in May.

The sequel reunited her with a number of her co-stars from the beloved 2006 original, including Meryl Streep, Emily Blunt and Stanley Tucci.

Now she is awaiting the release on Friday of Nolan's The Odyssey, which has been showered with rave reviews by Hollywood's critical fraternity.

However fan backlash has been mounting over the hiring of black performers Lupita Nyong'o, Zendaya and Travis Scott in an adaptation of a Greek epic.

Inasmuch as Scott is a rapper who had never held a major acting role before, his enlistment to play the bard was also criticized as a piece of stunt casting.

Trans actor Elliot Page has drawn scorn as well, on account of his inclusion in the picture as Sinon, who convinces the Trojans to let the horse into the city.

After holding its world premiere in London this Monday, the movie is slated for a theatrical release in both the US and UK on July 17. 

Nolan's adaptation of The Odyssey has been hotly anticipated for years, with an all-star cast including Matt Damon as Odysseus and Hathaway as his wife Penelope.

Tom Holland is featuring as the couple's son Telemachus, while his wife and Spider-Man co-star Zendaya is playing the goddess Athena.

Robert Pattinson plays Penelope's villainous suitor Antinous, with Samantha Morton and Charlize Theron as the witch Circe and nymph Calypso respectively.

Jon Bernthal plays the Spartan king Menelaus and Benny Safdie has been cast as his brother Agamemnon, the king of Mycenae.
