Harry Potter star Jessie Cave recalls awkward way she had to tell one-night-stand he got her pregnant

She might've starred in the world's most famous magical movie franchise, but the story as to how actress Jessie Cave got pregnant is far from a fairytale - by her own admission.

For those in need of a reminder, the 38-year-old is best known internationally for having played Ron Weasley's love interest Lavender Brown in the Harry Potter film series.

In the years since, Cave has since forged herself a prominent career in stand-up comedy, with her scripts largely being inspired by her real life romantic endeavours.

The British star appeared on the Have A Word podcast over the weekend, where she walked listeners through the 'one night stand' that changed her life.

The interaction in question was enjoyed with fellow comedian Alfie Brown, whom she worked alongside at the Edinburgh Fringe Festival in 2012.

Despite the two having worked in the same circles for some time, the two ended up in bed together following a date.

In the weeks that followed, the pair went their separate ways, opting not to communicate via text.

That was, until four months later, however, when Cave discovered she was expecting.

Speaking on this week's show, she confessed: "I didn't tell him I was pregnant until I was four months pregnant."

Asked how she broke the news to Brown, she claimed she fired off a text during a train journey. Tragically, however, the vehicle lost signal, 'so the texts didn't go through in the right order'.

Cave continued: "The first thing I text him was, 'Hiya, we need to talk'. I didn't want to be rejected because I needed him to talk. I was trying to do a text that was like sexy and aloof, but 'you have to meet me'."

She claimed that Brown then wrote back a rather blunt replying asking if she was 'pregnant or diseased'.

"I text back, 'Look, I didn't want to tell you this way but I'm pregnant, and I'm 16 weeks along. I'm calling it Bam, and it's a boy."

Unfortunately, given the train's laggy signal, the only message that sent through was an ultrasound scan photo of Cave's baby boy.

"All he gets is the scan photo of this human that he's made, and then the other texts just don't go through for like an hour.

"I had to tell him by text in the end."

Despite their awkward announcement, Cave claimed Brown went on to become quite the doting dad to their son Donnie - oh, yeah, they changed his name.

So much so, that in the years since, they've enjoyed an on-again-off-again relationship, and welcomed a further three children - daughter Margot, born in 2016, and sons Tennessee, born in 2020, and Becker, in 2022.
