The runner-up to Taylor Hicks on the fifth season of American Idol in 2006, Katharine McPhee, has parted ways with RCA after an album, a 2007 self-titled affair that debuted at No. 2 on The Billboard 200. Thus, she joined fellow "American Idol" contestants Taylor Hicks and Ruben Studdard as former members of the Sony BMG family.

"The demos, it's so hard once you hear whoever is singing to get that out of your head, especially for me, being new to recording," she said to Billboard.

Just last week, season-five victor Taylor Hicks was dumped by J Records, in what was described as a "mutual" split, while late last year, "American Idol" season-two champ Ruben Studdard was also chopped from the J Records roster. Apparently, Sony BMG has rid of its less profitable singers.

"American Idol" winner Katharine McPhee and her boyfriend, actor Nick Cokas, reportedly got engaged in November, after dating for two years. The couple, who met on the set of Los Angeles theater production “The Ghost and Mrs. Muir,” is allegedly heading for marriage.

After they met in 2005, McPhee, 23, and Cokas, 42, started their relationship as friends but they soon began dating after he accompanied her to her San Francisco "American Idol" audition. Once they started dating publicly, McPhee revealed in an interview last year that she hoped to keep her private life private.

Katharine McPhee was named one of the 100 Most Beautiful People of 2007 by People Magazine. She was also voted #2 on FHM's 100 Sexiest Women in The World of 2007 and was #47 on Maxim's Hot 100 Women of 2007. On Jan. 3, she sang the National Anthem before a national audience in Miami, Florida, at the FedEx Orange Bowl game between the Virginia Tech Hokies and the Kansas Jayhawks.
