It's not enough that model Heidi Klum and her singer husband Seal renew their marriage vows each year on their anniversary.

Now the supermodel has gone a step further and has etched a permanent reminder of her love for her husband of three years, inking a tattoo of his name on the inside of her right arm.

Heidi stepped out revealing the tattoo as she left her home in New York yesterday.

Wearing a sleeveless black and white print maxi dress, and fashionable gladiator heels, the mother of three children, Erna, Leni and youngest Johan, declared her love for husband Seal on her inside arm, in flowing calligraphy.

The swirly tattoo should come as no surprise as the lovey-dovey couple have revealed that they celebrate their wedding anniversary each year on the same beach where they exchanged vows in 2005, with the same minister.

Heidi and Seal renewed their vows in the same spot in Costa Careyes, Mexico in 2006 and 2007, and are making plans to return there next month.

Seal told InStyle magazine: 'It focuses us on why we got married, and sets a good example... for the kids.'

The couple owns a cliff-top estate overlooking the Pacific Ocean close to where they wed.
