Hollywood producer Brian Grazer is planning to wed again after proposing to his businesswoman girlfriend Veronica Smiley over the weekend (26-27Apr14).

The movie mogul popped the question on Saturday (26Apr14) in Santa Monica, California, but the proposal hit a small snag when Grazer misplaced the ring he had hoped to present to his bride-to-be.

A source tells the New York Post, "Somehow, the ring fell out of Brian's pocket. After a frantic search he found it, but only because it was such a big diamond, it didn't fall through the slats on the wooden floor."

This will be the producer's fourth marriage - he divorced his third wife Gigi Levangie in 2009.

Grazer was also engaged to Vietnamese concert pianist Nguyen Thi Chau Giang in 2011.

Smiley was previously linked to British funnyman John Cleese.
