Millie Mackintosh showed off her toned physique in black workout gear as she hit the gym on Friday following her split from her husband, Hugo Taylor. 

The former Made In Chelsea star, 36, looked incredible in a black sports bra and matching skin-tight leggings as she took a quick selfie break while working up a sweat. 

Flaunting her taut midriff, Millie completed the sporty look with chunky black-and-white Nike trainers. 

Sharing the sizzling snap to her Instagram Story, the star captioned the post: 'Friday let's go,' alongside a flexed biceps emoji. 

It comes as Millie and Hugo, 39, have reportedly filed for divorce following their shocking split after seven years of marriage. 

They are said to have both appointed legal teams, with the pair keen for a 'clean break' while continuing to co-parent amicably. 

They quietly separated after a 'difficult year' following struggles in their marriage, which were believed to have been heightened by Millie's admissions about her sexuality. Read the full story here. 

A source said: 'Fans will be sad to hear that their relationship is really over, but the pair just want a clean break.

'Millie and Hugo are committed to co-parenting their two young children and keeping everything stable. They are still very amicable with each other and have a lot of respect for one another.'

They went on to tell The Sun: 'They want the divorce to go through as painlessly as possible and are focusing on work in the meantime.' 

The Daily Mail contacted Millie and Hugo's representatives for comment. 

The couple - who met as teenagers and first dated during E4's Made In Chelsea - had been married since June 2018.

A source told the Daily Mail: 'Millie and Hugo are currently going through a separation and have sadly decided to split. 

'They have known each other for many years, and in recent weeks, have had serious conversations about their future, ultimately deciding it's better for them both to part ways.

'Their main priority remains their children and family life, and separating is not something they ever hoped would happen.

'At present, they are considering what living apart might look like and how they plan to navigate co-parenting their young children.

'It's been an incredibly difficult start to the year, and one they hope to continue managing in private.'

Sources close to Millie and Hugo say they remain committed to co-parenting their young children, who continue to be their priority, and to maintaining a loving family life.

Millie travelled to India last month to attend a wellness retreat designed to 'heal' the nervous system, while Hugo was on a skiing holiday.

During her stay, the reality star, who was pictured without her wedding ring, shared several posts alluding to a new chapter in her life.

She also posted a quote that read: 'You don't always have to know what comes next in your journey. 

'Sometimes you just need to be where you are and know that it's okay to be there. There is so much beauty in accepting yourself, right here, in this moment.

'No matter what you are working towards, I hope you can always remember that finding peace in the present moment is just as important as the path ahead.'

In another Instagram story, she shared the quote: 'And then the moon said to me, dear girl, it's time to own your f***ing power.'  

The couple's relationship was first followed on Made In Chelsea. 

After six months of dating, their relationship hit a wall when Millie accused him of cheating with her best friend and co-star, Rosie Fortescue, and they split in 2011.
