LONDON (AP) _ Oasis star Noel Gallagher is separating from his wife, Meg Mathews, after three years of marriage.

A spokeswoman for the guitarist said Tuesday the couple had ``simply drifted apart over the last year or so.'' She said the pair had no immediate plans to divorce.

The couple have an eight-month old daughter, Anais.

Their separation follows the announcement in July that Noel Gallagher's younger brother and bandmate Liam had split up from his wife, actress Patsy Kensit.

Oasis just concluded a world tour amid rumors that the band was breaking up. Noel Gallagher, who writes the bulk of the band's songs, walked away from the tour in May after disagreements with his brother.

At the time, he said he left the band to spend more time with his wife and newborn daughter.

``I don't like the way that people are blaming it on the fact that I want to spend more time at home,'' Noel Gallagher said during a British Broadcasting Corp. radio interview. ``If you tasted my wife's tea you wouldn't.''

He later rejoined the group for its final concerts in Britain.
