Robbie Williams 'to marry his American girlfriend'

Robbie Williams will marry his American girlfriend tomorrow, it was reported.

The singer, 36, will tie the knot with Ayda Field, 31, on an island off the coast of California, The Sun said today.

According to the paper, Williams' Take That bandmates - who he dramatically rejoined last month - are not attending the "intimate" ceremony on Santa Catalina.

Among the guests said to be attending are his parents, and friend Jonathan Wilkes.

Los Angeles-based Williams and Field have been together for more than three years since meeting through friends.

They are reportedly going on a two-week honeymoon before he arrives back in the UK to promote the new Take That material.

His previous girlfriends include model Rachel Hunter, pop star Nicole Appleton and actress Anna Friel.

Last month Take That ended months of speculation by announcing Williams was rejoining the band for a new album. He walked out 15 years ago.
