FERGIE of the Black Eyed Peas

The singer and her actor fiance announced their engagement on Christmas Day (25Dec07), and although she's yet to start planning her nuptials, Fergie isn't sure if she can keep from spilling the secrets herself.

She says, "I'm thrilled. But I'm not giving any details - I think the fine points are sacred.

"But it's hard for me because I have a big mouth."
