Shania TwainCountry singer Shania Twain is engaged to wed Swiss Nestle executive Frederic Thiebaud, her reps confirmed to Us Weekly. Thiebaud popped the question about two months ago in Switzerland.

Twain stepped out with Thiebaud at Serafina's Fabulous Grill in NYC on Thursday with an enormous engagement ring.

Although it's happy news, it's filled with scandal. Thiebaud is the ex-husband of Twain's former best friend Marie-Anne Thiebaud -- the woman Robert "Mutt" Lange, Twain's husband of 14 years, abruptly left her for in May 2008.
