E! News reported that McPhee posted on Twitter about the news with an engagement ring emoji and a gif of Ariana Grande saying, "And what about it?"
This will be the second marriage for McPhee, who was married to actor Nick Cokas from 2008 to 2016. It will be the fifth marriage for Foster. He was married to musician B.J. Cook from 1972-1981, model Rebecca Dyer from 1982-1986, actress and songwriter Linda Thompson from 1991-2005, and model and TV personality Yolanda Hadid from 2011-2017.
Foster and McPhee have been friends since they met on the set of “American Idol” in 2006. They reportedly started dating last September.
