London, Feb 3 : Superstar singer Madonna is all set to renew her marriage with husband Guy Ritchie during a summer ceremony.

The couple's decision is said to be aimed at scotching speculations that their seven-year marriage is on the rocks.

Only close family and a small selection of celebrity pals, including Gwyneth Paltrow and Stella McCartney, will be invited to the private service at the couple's Wiltshire home.

According to sources, fashion designer Stella has designed the singer's wedding outfit, which will be a cream trouser suit.

Paltrow and Madonna's 11-year-old daughter Lourdes will do a reading.

Madonna and Ritchie are said to have bought each other eternity rings, but are keeping their plans under wraps. "Renewing their vows is the one way Guy and Madonna can show the world they are strong," News of the World quoted a source as saying.

"They've worked hard to iron out their differences to get through the tough times. It's going to be a very emotional day and that's why they want the people who are closest to them to share it with them," the source added.

The couple, who got married in 2000, have constantly been dogged by rumours of marital woes.

"They know a strong marriage takes constant effort and that they're in it for the long haul," the source added.
