NEIL DIAMOND ENGAGED, ANNOUNCES ON TWITTER

Third time's a charm!

Neil Diamond -- who's been married twice before -- is set to wed his co-manager Katie McNeil. The 70-year-old "Sweet Caroline" singer made the announcement via Twitter Wednesday.

"Good news coming from sunny LA/ and you're the first I want to tell/ Katie and I just got engaged/ and I hope you wish us well," he wrote.

The "lovestruck" singer then tweeted a photo of his bride-to-be, taken "in London last month."
