Millie and Hugo Reunite for Daughters Birthday

and estranged husband  reunited at daughter Sienna's sixth birthday, months after their shock split.

The Daily Mail revealed earlier this year that the  stars, who share Sienna and four-year-old Aurelia had separated after seven years of marriage.

It was later reported that they officially filed for divorce and both appointed legal teams, with the pair said to be keen for a 'clean break' while continuing to co-parent amicably.

Millie, 36, and Hugo, 39, posed proudly alongside their 'darling daughter' who was celebrating with a KPop Demon Hunters' themed party. 

Sienna was in fancy dress, while Millie looked stylish in a sparkly halterneck top with jeans while Hugo opted for a casual green shirt.

She captioned the post with a gushing birthday tribute which read: 'My baby is SIX'.

'I genuinely don’t know where the time has gone. It feels like I blinked and we went from the newborn haze to this brilliant, funny, sassy, kind, strong little girl who takes my breath away every single day'. 

She continued: 'Six years ago I was pregnant, wondering what life on the other side of lockdown would look like. What she would look like. Who she would be. We’ve gone from princess dresses and tiaras to K-pop demon hunter crop tops, and I have to say, every era has been my favourite era'. 

'The leap from 5 to 6 has felt like such a significant one. She seems so grown up, so confident, so wonderfully and fiercely herself. She makes me laugh every single day. She surprises me, moves me, and fills our home with so much joy and life'.

Before adding: 'Sienna, you are without question one of the greatest things that has ever happened to me. Being your mummy is my biggest privilege. I love you more than any words could describe. Happy 6th birthday my darling girl. Here’s to every chapter ahead'.

It comes after  opened up about 'self medicating' with while undiagnosed with as she also opened up about her panic attacks in a new interview.

The reality star-turned influence is celebrating four years sober this summer, having quit booze in 2022. She was undiagnosed with ADHD during her time in school, which she said made her years in education 'really difficult' as a result, going through five different schools.

Millie was also in her early teens when she discovered alcohol, admitting she used it 'as a mask' for a persona she thought people would like and find acceptable. 

She explained: 'That [alcohol] was the most accessible medicine I could find it was also socially acceptable and you're encouraged to drink and have, you know, a couple of drinks.

'I'd reached that point where my brain just slowed down like there wasn't suddenly all this noise and I had that relief and then I just wanted to keep that feeling and then, you know, I just wanted to keep drinking, keep drinking, didn't really have an off switch.'

Millie said once she stopped drinking, she needed to 'take the mask off'. 

She continued to the Spooning with Mark Wogan podcast: 'When you're learning to socialise and you're using alcohol to feel comfortable about yourself and who you are and you're actually masking who you actually are and you're not, you don't even really know who you are yet, but you're becoming somebody that's not very authentic.'

Two years after giving up alcohol, Millie  

Speaking to Claire Sanderson and  for Women's Health UK earlier this year, Millie insisted she had to 'completely abstrain' from booze because she couldn't handle having just one drink. 

Asked if she would describe herself as an alcoholic, she replied: 'I think it depends what your definition is.

'I wasn't a drinker who depended on drinking alcohol everyday of the week but whenever I drank I wanted to drink to black out and drink, and drink, and drink.

'I recognise that urge is very unhealthy for me and it is better for me to completely abstain than to have the option of having one.' 

Meanwhile, the mother-of-two also opened up on her scary panic attacks, revealing she can experience three different debilitating symptoms.
