MILAN - Madonna has teamed up with Italian fashion house Dolce & Gabbana to design a collection of sunglasses.

The first six styles of the pop diva's MDG line will be launched in May, the fashion house said Tuesday.

The singer designed the collection in collaboration with Italy's most famous designer duo Domenico Dolce and Stefano Gabbana and will also be the face of the MDG advertising campaign.

Fifty-one year old Madonna already appears in a campaign for the designers.

Bearing the MDG logo, the collection marks Madonna's first foray into the world of eyewear. She has previously collaborated with high street brand Hennes & Mauritz for a clothing line.
