It looks like American Idol runner-up Katharine McPhee isn't keeping her engagement to actor Nick Cokas, 42, under wraps anymore. Rumors were circulating that the 23-year-old singer-actress had been engaged since March to her boyfriend of more than a year and was keeping it a secret. But friends are now reportedly saying that Katharine is showing off an engagement ring with talk that she is planning a February wedding. For now, the couple are teaming up on an independent film titled The Last Caller. Katharine is starring while Nick is producing. Congrats!
