Gwen Stefani and her rocker husband Gavin Rossdale are secretly planning to tie the knot again to celebrate their 10th wedding anniversary.

A friend of the singer, 42, told the Daily Star newspaper: ''Gwen and Gavin are going to remarry on September 14. They feel like they've fallen in love all over again.''

Gwen, who got married to Gavin, 46, in 2002 in Covent Garden, London, is also telling friends she is considering adopting to add to their own brood of two children.

Apparently the main reason she is choosing that route is because she feels she may be getting too old to bear a child herself.

The insider continued: ''They'd also love another baby, but Gwen thinks because of her age adoption is the way forward.''

The No Doubt singer recently revealed the band had just made ''the album of our lives''.

The 'Don't Speak' hitmakers are confident their first record in eleven years, 'Push and Shove', is worth the wait and are ''so proud'' of the finished product.

Gwen told ''We would've loved for it to come out sooner.

''At the same time, we realised the people that care about us, that have given us our lives, are out there waiting for us, so what does it matter if it's a month here or a month there?

''As long as we make the record of our lives that we are so proud of. Otherwise, why put something out?''
