“American Idol” season five runner-up Katharine McPhee, 23, got married to her boyfriend of nearly three years Nick Cokas, 42, at Beverly Hills Presbyterian Church on Saturday. The pair never officially announced their engagement, though “sources” said they were engaged in November, and the pair were caught checking out wedding cakes in May. Several of McPhee’s fellow “American Idol” contestants attended the wedding, including Kellie Pickler and Mandisa.

“(Nick) is the love of my life,” McPhee gushed to PEOPLE. “This is a once in a lifetime occasion and everything is just perfect.”

McPhee wore a strapless ivory Manuel Mota gown and Neil Lane jewels (diamond and platinum chandelier earrings and diamond and platinum bracelets), while Cokas wore an Armani tuxedo. Fellow season five Idol contestants Kellie Pickler and Mandisa were among the 305 guests on hand for the nuptials.

McPhee and Cokas met in 2005 when they performed in a Los Angeles theater production of The Ghost and Mrs. Muir. Their union began as a friendship and blossomed when McPhee auditioned for American Idol later that year.

The two quietly got engaged last year when Cokas presented her with a custom-designed round brilliant cut platinum and diamond engagement ring.

The service was 45 minutes long and included a gospel choir. Katharine’s bridesmaids wore floor-length pink dresses, and the church was filled with peach, white, pinks, and purple roses along with pink cherry blossoms and green hydrangeas. It sounds like they went all out. I really hope we get to see wedding photos soon. I’m sure Katharine made a gorgeous bride.

Though Katharine’s husband Nick Cokas is 19 years her senior, he’s definitely not her sugar daddy. He’s a broadway actor who also founded a small production company. Though Katharine seems a little on the younger side for getting married, they’ve been together long enough, and they always seem happy when they’re photographed out and about. Congrats to them both!
