Jessie let her lengthy blonde tresses flow loosely as they draped down to her waistline. 

She posted the photo alongside a caption that read: ‘Wondering if I would have had my hair cut by now if I could have.’

But a few hours later Jessie, who most well-known for playing Lavender Brown in the Harry Potter film series, revealed she had suffered an allergic reaction to almonds.

Taking to her Instagram story with a make-up free selfie, she told fans: ‘Having an allergic reaction to an almond in my mouth. Almonds were one of my safe nuts.’

It comes just days after Jessie spent the afternoon in hospital having been struggling with headaches and swollen ankles.

She said she had not suffered the same health problems in her previous pregnancies but later reassured fans that she had been given the all-clear.

The on-screen star first announced she was expecting her third child last month with partner Alfie Brown.

In a slew of snaps posted to her Stories, Jessie revealed she’d been admitted to hospital and was waiting to be seen by doctors so they could check her baby’s heartbeat.

The star ensured she was safe by wearing a mask throughout, and praised NHS staff for taking such incredible care of her.

She told fans: ‘I’m in the hospital waiting for the doctor to check my swollen ankles,’ before playfully adding: ‘Nurse said she doesn’t think my ankles look that swollen… I wanted to say ”but my ankles are usually very thin. Like J.Lo’s”.’

Last month Jessie first announced she and partner Alfie were expecting their third child together.

In a sweet announcement post shared to Instagram, she looked as radiant as ever as her son Donnie, five, and daughter Margot, three, lovingly cradled her baby bump. 

The TV star’s partner also updated his social media followers on the happy news by uploading a picture of an ultrasound, alongside the cheeky caption: ‘I’m very happy to announce my forthcoming vasectomy.’

Black Mirror actress Jessie cut a chic figure in a yellow, off-shoulder top and a polka dot print skirt as she cupped her stomach.

‘Oops I did it again’, the thespian captioned her post, alongside a fallen leaf emoji, seemingly hinting at her baby’s autumn due date.    

Earlier this year, stand-up star Alfie revealed he and Jessie rekindled their relationship after splitting up when their youngest child was only 10 weeks old. 

On maintaining a healthy work-life balance, the media personality told Bustle in 2018: ‘I learned pretty early on you can’t do much work with children around.

‘When they were babies maybe, but now they don’t sleep so I’m basically on my feet the entire day. My mum is brilliant; she helps me most days. 

‘And, actually, up until a few weeks ago I was living with her and my sister. My partner Alfie and I split up when Margot was only 10 weeks old.’

The cartoonist, who juggles her stand-up and acting career with her successful ‘doodle’ company, famously became pregnant with her first child after a one-night stand with her on-off partner in 2014.

Jessie is best known for her role as Gryffindor student Lavender Brown in the Harry Potter film series, which she recently admitted did ‘nothing for my career’.

The Father Brown star told the Evening Standard: ‘It [Harry Potter] didn’t really give me a step up. 

‘I never intended to be an actress — I needed money and accidentally got the role. Well, I auditioned but I wanted to be a performance artist which is what I am doing now. So it did nothing for my career.’ 

In March last year, Jessie suffered the tragic loss of her brother Ben Haddon-Cave, 27, who was killed when he hit 25,000-volt overhead power cables while train-surfing following a drunken night out.
