revealed she is 'rebuilding myself to be stronger than ever' as she shared a series of gym selfies on Instagram on Thursday.
The former star, 38, showed off her toned physique in a plunging red sports bra and matching leggings after working out in her home gym.
Fans told Billi she looked like she was 'glowing from the inside out', while others told her that her figure is the 'ultimate revenge' following the breakdown of her marriage to footballer Andy Carroll, 37, in 2024.
The ex-Premier League star is in a relationship with make-up artist Lou Teasdale, 42, after they reportedly met at Festival two years ago.
But insiders fear Andy's new job as the manager of Dagenham & Redbridge football club could cause tension between himself and Lou.
The couple have jetted off on frequent holidays as the striker has had an injury since December.
However he now will have to focus on his new role and might have to make 'sacrifices' when it comes to their romantic trips abroad.

'It's well known Lou and Andy enjoy a life of luxury – and who could blame them. They've gained a reputation for their expensive holidays and desire to jet-set all over, having the time of their lives,' a source told The Sun.
'But as a manager, Andy knows he will really need to step up to the plate and act as an example to his players. Especially if there's the chance to make it a full-time gig.
'This is an incredible opportunity he's been handed, and he doesn't want to mess it up – but it comes with sacrifices.'
Daily Mail has contacted Andy and Lou's representatives for comment.
It was revealed on Thursday that sacked the manager of Dagenham & Redbridge and replaced him with Andy just two weeks after buying the club.
The social media star has made the first major move of his reign at the National League South side by ditching Lee Bradbury, 50.
The team are currently 12th in the division.
A club statement read: 'Dagenham & Redbridge Football Club can confirm that we have parted company with First-Team Manager, Lee Bradbury.

KSI has appointed Andy Carroll as the new Dagenham & Redbridge interim boss - the pair were seen watching the team during a win over Dorking earlier this month
'We are very grateful to Lee for his focus, professionalism, and commitment during his time at the Club and for his contributions, both on and off the pitch, to stabilise the club last summer.
'Dagenham & Redbridge wish him every success in his future endeavours.
'Andy Carroll will take the team on an interim basis, and further updates will be communicated in due course.'
The new job comes as Andy is due to stand trial next January after pleading not guilty to breaching a non-molestation order having been accused of repeatedly calling Billi, with whom he shares three children.
A non-molestation order is handed out at civil court and designed to stop someone going near another person.
Breaching a non-molestation order can lead to a maximum of five years in prison.
