Ripped Megan Fox shows off her stunning six-pack and a new tattoo

She has consistently topped the lists of world's sexiest female. But who knew Megan Fox was hiding such a ripped body under those red-carpet dresses?

The former Transformers star unveiled her taut body on the beach in Hawaii as she enjoyed a romantic break with her boyfriend Brian Green.

And that wasn't the only surprise, as the pin-up revealed a new tattoo on the right side of her body. The 24-year-old actress put her sleek figure on show in a brown bikini as she frolicked in the Maui surf with her boyfriend, the former Beverly Hills 90210 star - himself no stranger to body art.

And it gave onlookers the opportunity to get a good look at her ninth tattoo.

The new inking over the right side of her rib cage reads: 'Those who danced were thought to be insane by those who could not hear the music.'

The tattoo is taken from a quote by little known poet Angela Monet - although it could well be a paraphrase of 13th century Persian poet Rumi, who said: 'We rarely hear the inward music but we're all dancing to it nevertheless.'

And it's proof if ever it was needed that Ms Fox takes herself more than a little seriously.

Clearly a fan of wordy inkings, she's fast turning herself into a walking book.

Her right shoulder is adorned with a line from Shakespeare's King Lear which reads: 'We will all laugh at gilded butterflies.'

And her left ribs act as the perfect bookend to her latest addition - she has the self-penned words: 'There once was a little girl who never knew love until a boy broke her heart.'

Earlier, she emerged on the beach in a mismatched black polka dot bikini top and turquoise bottoms.

And it was surely a welcome break before she begins promotional duties on her next film.

Megan's next project sees her star opposite Oscar nominees Josh Brolin and John Malkovich in the supernatural Western Jonah Hex. It is due for release on June 18.

No wonder she hit the gym!
