She was fired from Transformers in 2011, after rocketing to fame as their sizzling siren in 2007. And ten years on, Megan Fox has admitted she regrets the behaviour that led up to her leaving the Transformers franchise, describing it as a ‘low point in her career’. Megan, who has been married to 90210 actor Brian Austin Green, 44, since 2010, also opened up about their relationship, after calling off their divorce while pregnant with their third child last year.

Posing as Cosmopolitan’s December cover star, Megan- who Rosie Huntington-Whiteley for the third movie replaced, describes the end of her contract with the action flick as a low point in her career. Slipping into a plush pale pink faux fur jacket, she admits:’That was absolutely the low point of my career. But without – ‘that thing’ – I wouldn’t have learned as quickly as I did.’

All I had to do was apologise – and I refused. I was so self-righteous at 23, I couldn’t see [that] it was for the greater good. I really thought I was Joan of Arc.’ Another shot sees the actress slip into a semi-sheer chiffon black dress and funky trainers, as she opens up about her previously tumultuous relationship with husband Brian, she admitted having to work to keep things going 13 years after they first met.

Megan is also a step-mum to Brian’s 15-year-old son Kassius from his previous relationship with Vanessa Marcil. And changing into her final ensemble- a satin strapless gown dressed down with trainers, the raven-haired beauty reveals her busy personal life comes before her work life.
