The country star has been publicly criticized by his ex-wife since announcing his engagement to the jewelry designer last week.

Brown and Scott are engaged after the country singer popped the question with a sparkling pink diamond for the jewelry designer.

When country superstar Zac Brown popped the question to jewelry mogul Kendra Scott on July 24, he didn't buy his ring from just any jeweler. He turned to Houston's Valobra Master Jewelers, a longtime trusted source for custom pieces and one-of-a-kind showstoppers.
