The former American Idol victor confirmed the news through her rep Leslie Sloan, however, later took to Instagram to share the announcement herself. It's unclear exactly which day he proposed, but we imagine it was shortly before this pic was taken.
A representative for McPhee confirmed the engagement to Yahoo Entertainment on Tuesday. "What did I miss?" wrote Sara.
Congratulations are in order for Katharine McPhee and David Foster!
Foster and McPhee have been linked since past year, when they were spotted on a dinner date in Malibu.More news: USA representative from Wisconsin proposes dismantling of ICE
Foster, 68, popped the question to McPhee, 34, while the two were vacationing in Italy, according to the former "Smash" star.
McPhee also shared a post from the boat ride, slightly poking fun at her photographer.
Foster and McPhee would soon appear together at a wedding reception, but this time as husband and wife.
The musical pair first sparked romance rumors in September 2017, after the latter's daughter Erin Foster shared a photo of them together in Los Angeles. "I love his outlook on life and how he treats people".
Foster was previously married to Linda Thompson, Rebecca McCurdy, B.J. Cook, and model Yolanda Hadid, who he divorced in October. Mcphee was also previously married for eight years to actor Nick Cokas.
