All the times Katharine McPhee made us laugh

Katharine McPhee unleashed her inner Meredith Blake in a Parent Trap moment — and it was super funny.

On August 30, 2018, McPhee shared an Instagram photo of herself on holiday. David Foster’s daughter Erin commented, “CHIC,” and a fan asked Erin if it was “awkward” that McPhee is two years younger than her.

Erin replied, “I’ve started saying I’m 31, so now she’s 3 years older than me. I’m a problem solver.”

McPhee then responded to Erin, quoting The Parent Trap.

“Stop blowing my age cover! The day we say I do, I’m shipping you and your sister off to Switzerland,” wrote the singer.

“Omg you’re gonna parent trap us!!! I knew it,” Erin replied.
