Katharine McPhee Went Wedding Dress Shopping With Another One of David Foster's Daughters

At 34 years old, Katharine McPhee is about to become a stepmother of five. Her husband-to-be David Foster has as many daughters, ranging in age from 32 to 48. And while that could be — how do we put this gently — a little awkward, it looks like the Fosters are shaping up to be one big happy, modern family. 

Foster's daughter Sara has already been public about her close relationship with McPhee, using Instagram to affectionately rib her for her taste in swimsuits. Sara's sister Erin has also called out her future stepmother's poolside style. And now, it looks like the Waitress star is bonding with her fiance's youngest daughter, as well. 

Jordan Foster is a stylist who's putting her expertise to work as Katharine's bridal-shop wing woman. In a January 16 Instagram post, the bride-to-be showed off a gown she had tried on, but ultimately not chosen for the big day. In her caption, McPhee wrote: "Wedding dress fittings today with [Jordan Foster]! It was such a happy day. (It’s not the dress, but just wanted to share.)"

This isn't the first time Jordan has lent her styling expertise to McPhee. Back in October, she shared a photo of the American Idol alum with this cute caption: "[Katharine McPhee] threatened to ground me if I didn’t style her. [Love] u mommy!"
