Katharine McPhee is living it up ahead of her wedding to David Foster.
The "American Idol" alum posted several pictures of herself partying on a boat in Mykonos, Greece.
In the photos, McPhee dons a neon rainbow tutu among other colorful accesories while sipping a beverage.
"Honey this is how you throw a party in Mykonos b---h!!" she captioned her post.
The 35-year-old singer is engaged to marry her music producer, Foster, who is 69. She recently got rowdy at her #katchelorette party which included male strippers.
She was surprised by her close pals for a bachelorette after one of her May performances of "Waitress" in London’s West End.
"Casually walked off stage to this," McPhee to her Instagram story at the time along with a photo of herself getting a lap dance.
Foster popped the question to McPhee while vacationing in Italy last summer. It will be the second and fifth marriages for the bride and groom, respectively.
