The stars were rocking Cartier at the Rodeo Drive Walk of Style Awards in Beverly Hills on Thursday night.

Decked out in diamonds, Demi Moore singled out one piece that stands above the rest. Pointing to her ring finger, she said,

Debra Messing told ET her true feelings towards Princess Grace, saying,

“You can’t think of fashion as we know it without thinking of Princess Grace.   She is glamour.   She is Hollywood. She’s modern, elegant, sophisticated, and graceful, no pun intended. She really defined a whole era…”
