Third marriage ... Neil Diamond and Katie McNeil.

Third time lucky? ... Neil Diamond and Katie McNeil.

Neil Diamond has married for a third time after exchanging vows with Katie McNeil on Saturday.

The 71-year-old singer walked down the aisle with his co-manager, who, at 42 is almost 30 years his junior, at a private location in Los Angeles.

A representative for the star confirmed the news to People.com, revealing the wedding was a small affair and involved just close friends and family.

Diamond announced the engagement via Twitter in September, and he vowed to tie the knot before he headed out on tour this year.

The veteran crooner was previously married to his high school sweetheart, teacher Jayne 'Posey' Posner, but they split in 1969 after six years as man and wife. He divorced his second wife Marcia Murphey in 1995.

Diamond has two children from each marriage.
