David Foster and Katharine McPhee are married one year after the two announced their engagement.
The couple said "I do" in front of 150 members of their family and friends in London on Friday.
150 people watched the groom, 69, and bride, 35, exchange vows at the Church of Saint Yeghiche in South Kensington.
McPhee reportedly wore a Zac Posen wedding gown and Foster sported a tux by Stefano Ricci.
Hours before they tied the knot, the actress shared a post thanking David for bringing her into his life.
"Exactly 13 years ago today my very first single, Somewhere Over The Rainbow, was released right after Idol. Today... I’m marrying the man who produced it," she wrote. "Life is full of beautiful coincidences, isn’t it? Thank you for taking me over the rainbow, David."
This morning she also showed herself getting a facial joking that the treatment plus Xanax equals a calm bride.
"The secret to a calm and collected bride. And maybe a little Xanax," she wrote.
The music producer popped the question to the "American Idol" alum last summer during a romantic getaway to Italy.
Foster and McPhee were first linked in 2017 around the time his divorced from Yolanda Foster was finalized.
This is David Foster's fifth wife. Besides Yolanda, his other famous ex includes Linda Thompson (who was also married to Caitlyn Jenner when she was Bruce).
Foster has five grown children and the actress meshes well with his large family.
Two of his daughter's -- Erin and Sara -- are extremely close with McPhee, even playfully calling her "mom."
This is Katharine McPhee's second marriage. She wed actor Nick Cokas in 2008 before a very public divorce in 2016.
Congrats to the happy couple!
McPhee showcased she's a blushing bride, posting the first photo in her wedding gown!
Sitting next to her mom -- Patricia -- the songbird snapped a selfie in the back of the car on the way to the venue.
Sporting the strapless gown with a sweetheart neckline, she opted for her hair pulled back and swept off her face. McPhee wore a pink palette with blush lipstick and minimal eyeshadow for her big day!
