According to a source close to singer Katharine McPhee, the 23-year-old American Idol runner-up was married to her boyfriend, actor Nick Cokas in a ceremony in Los Angeles on Saturday.

In September, OK! was the first to reveal that Kat and Nick, who is 19 years older than his new bride, were engaged. And only a few weeks ago, the singer confessed to OK! that she was desperately trying to get in shape for the wedding.

"I do 20 to 30 minutes of cardio three times a week if I’m lucky, four times if I’m really lucky," Katharine told OK!’s Red Carpet Confidential blog. "I just started doing lunges with dumbbells, and I just started doing shoulder stuff, arm stuff, back stuff.”
