The tattoos were on show as the brunette actress revealed her long limbs and toned body in a slit to the thigh asymmetrical red dress.

The inkings are two of the eight on her body – and if U.S. reports are to be believed, she could soon have many more.

Megan is apparently planning on getting a tattoo sleeve – where her arm would be completely covered in the etchings.

But her mother Darlene is begging her to reconsider – fearing the body art will put off movie bosses and jeopardise her career.

A source told the National Enquirer: ‘She has never understood why her daughter would want to cover her gorgeous body with tattoos.

‘After each new tattoo, Darlene pleaded with Megan not to get more. Darlene believes that when Megan is a 40-year-old woman wanting to play more mature roles, people won’t want to hire her because it will be too hard to cover her tattoos.’

But as Megan walked the red carpet at the Berlin premiere of Transformers: Revenge Of The Fallen her tattoos didn’t stop the hordes of fans clamouring for her autograph.

The 23-year-old claims she didn’t work out before filming the movie – and only now is she ditching the junk food for a healthier way of life.

‘I’m a big sugar addict and junk food addict and just recently started trying to be a really healthy-type human being,’ she told the Insider.

‘Honestly, my bodyweight and muscle tone fluctuates constantly. I wasn’t super ripped or in shape in that movie.

‘I just started working out now so I’m getting better.’

The U.S. actress, who dates former Beverly Hills 90210 star Brian Austin Green, spoke of her chemistry with Transformers co-star Shia Labeouf.

‘I just always want to hold him and take care of him and make sure he’s happy and safe and kiss him on his forehead,’ she revealed.
