Neil Diamond is engaged to his manager, Katie McNeil. The 70-year-old crooner tweeted the news yesterday, “Good news coming from sunny LA/ and you’re the first I want to tell/ Katie & I just got engaged/ and I hope you wish us well.” He then posted a photo of his new fiancée, who produced Diamond’s 2009 documentary, Hot August Night/NYC.

This will be the third marriage for Diamond, who has four adult children.
