Katharine McPhee has bachelorette party with strippers ahead of David Foster wedding

It’s Katharine McPhee‘s #katchelorette party and she’ll get rowdy if she wants to.

On Saturday, the future Mrs. David Foster was surprised with a bachelorette bash from close friends following her performance in “Waitress” in London’s West End.

“Casually walked off stage to this,” McPhee, 35, posted to her Instagram story.

McPhee, who got engaged to Foster, 69, while vacationing in Italy last summer, was still dressed in her costume from the show when she received the news about her party, which later included a dance from a stripper clad in firefighter gear.

“Not your average backstage meet & greet,” McPhee quipped.

The evening continued with sing-alongs to Britney Spears and Whitney Houston, as the bride-to-be celebrated with her inner circle.

“The future is happy and bright #katchelorette,” McPhee also shared with her Instagram followers.

McPhee’s future is bright indeed, as the actress and Foster want to tie the knot in London sooner rather than later.

“She really wants to get married and doesn’t want to wait,” an insider previously told Page Six.
