David Foster‘s daughter Erin appears to have inducted her father’s rumored girlfriend, Katharine McPhee, into their family.
Foster, who has been married four times, was honored at this week’s 2017 Grammy Museum Gala, where he performed with McPhee. Also in attendance was Erin Foster, who took to Instagram to show her approval of her dad’s relationship with McPhee.
“Excited about my new stepmom,” Erin captioned a shot of the “American Idol” runner-up and her dad.
Erin — who at 35 is two years older than McPhee — also posted a video of the pair’s performance with the caption “parents.” (Erin’s actual mother is Rebecca Dyer.)
In May, Foster, 67, and McPhee were spotted having a “very intimate dinner” at Nobu in Malibu. Although a source told E! News, “David was seen grabbing Katharine’s face and kissing her cheek several times,” her rep told us at the time that they have known each other for 11 years and are just friends.
Foster was most recently married to Yolanda Hadid, who filed for divorce from the musician in January 2016.
A rep for McPhee did not respond to Page Six’s request for comment Friday.
