Brooke Burke and Baywatch hunk David Charvet are back from their Caribbean honeymoon, and the bride is proud to show off her new wedding sparkler. Burke and Charvet tied the knot off the coast of St. Barts in a secret ceremony.

The sexy newlyweds strolled in Malibu, arm in arm, to do a little shopping ... even stopping at a jewelry store. Is Brooke already looking to add more diamonds to her already gigantic band? Watch out, David!

Brooke and David have been together since 2005. They have two children ... daughter Heaven, 4, and son Shaya, 3.
