"It's a yellow sapphire," she said. "The View" co-host told how Wahlberg, star of CBS' "Blue Bloods" and a member of New Kids on the Block, proposed to her last weekend. She said her son, Evan, helped with the proposal.

"I feel like the luckiest girl in the world. He's so wonderful," McCarthy, 41, said.
