Katharine McPhee Tries On Wedding Dresses With Fiancé David Foster's Daughter

Katharine McPhee may be one step closer to marrying fiancé David Foster. The Waitress actress went wedding dress shopping Tuesday, January 15, with her future stepdaughter Jordan Foster and she shared a moment from their day on social media.

Katharine, 34, who got engaged to her music mogul beau in July, has remained mum on wedding details.

She does seem to be in the planning process, though. The Broadway star is searching for that perfect dress, and enlisted the help of her future husband's daughter to help her.

Katharine shared this picture on Instagram of her in a wedding dress. "Wedding dress fittings today with @jordiefos! It was such a happy day. (It’s not the dress, but just wanted to share) ❤️," she wrote.

There's a good reason the former American Idol finalist has Jordan helping her: she is a mega stylist who has dressed the likes of Ashley Graham and Kate Upton.

This won't be the first wedding for either the Scorpion actress or her man. Katharine was previously married to actor Nick Cokas and the "I Do's" will mark David's fifth marriage.
