In this day and age, a couple’s relationship isn’t official until it says so on their social media accounts.

Katharine McPhee Foster made her second marriage Insta-official last week when she changed her Instagram handle to her new married name.

The 35-year-old singer, who tied the knot with 69-year-old music producer David Foster just this June 28th, now goes by @KatharineFoster and isn’t worried about fans not being able to find her due to the name change.

Kat’s video interview with Extra above is from the Vocal Star Music Seminar held at Loews Hollywood Hotel in Hollywood last Sunday.

The American Idol runner-up was sleek in a black mesh halter top, black-satin high-waist pants, and with her honey-blonde hair in loose waves.

Keeping her jewelry to a minimum, Kat relied on her Jimmy Choo ‘Bing’ crystal-embellished mules to add some much-needed sparkle.

About a month before getting hitched, Katharine McPhee and David Foster attended the 2019 American Icon Awards together.

Kat was glowing in a shiny, bronze bishop-sleeved button-down top tucked into a matching maxi skirt.

She paired her look with nude-suede ankle-tie sandals studded with sparkling crystals on the x-straps.
