Going To The Chapel

American Idol alum Katharine McPhee, 23, and her daddylike-boyfriend, Z-list actor Nick Cokas, 42, are engaged!

Clay Aiken will be the bridesmaid and Julia D’Amato will do some stripper dance.

McPhee and Cockas have been dating for two years. They met pre-Idol when they starred in a play together.

Do people even care about Katharine any more????

Her recording career bombed! So did that Taylor Hicks!

Daughtry is laughing all the way to the bank.
