Happy anniversary, indeed!
“I have a very thoughtful husband with GREAT taste!!!!” Rimes, 29, Tweeted on Sunday with a picture of her new jewelry.
The ring must be icing on the cake for Rimes, who still seems to be enjoying her honeymoon phase with Cibrian, 38. The couple were spotted at a romantic lunch at Toscanova in Calabasas, Calif., on Friday.
