It seemsKatharine McPheedoesn’t mind being mixed up withSophia Bush— in fact, she takes pride in it!

On Friday, the singer, 34, posted ahilarious video to her Instagramfrom a red carpet event years ago, where she was accidentally mistaken for theOne Tree Hillactress. In the clip, a reporter calls over McPhee for an interview but refers to her as “Sophia” — which it seems McPhee does not initially hear — and then proceeds to say, “You’re inOne Tree Hill.”

McPhee was understandably confused at the time, but years later, decided to capitalize on the error. “if there’s ever a @sophiabush biography, y’all know who to call…” she jokingly captioned the video.

“I legitimately cannot stop laughing,” she wrote. “Also, not fair that it doesn’t go the other way! No one’s ever heard me singing and said “oh you sound just like Katharine McPhee” dammit!!”

Shortly after Bush’s funny comment, McPhee responded back to theOTHalum a joke of her own and referenced Bush’s character on the show, Brooke Davis.

“well then, if they ever make a one tree hill the musical, skip the casting process and reach out to my agent,” McPhee wrote. “i’d be HONORED to play Brooke.”

Bush was not the only person to poke fun at the situation.Erin Foster, who is the daughter of McPhee’s fiancéDavid Foster, also commented with a sarcastic response. “Im in awe of your talent, you can be so many people,” Erin, 36, wrote.

McPhee often jokes around on social media with Erin, especially when it comes to her relationship with her fiancé, 68.

Over the summer, theWaitressstar shared a photo from her Canadian vacation with Foster which caught the eye of Erin, who commented, “CHIC.”

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

And just a few days earlier, theAmerican Idolalum posted a photo from Stuart Island, British Columbia, writing, “Country album drops this week.”

Moments later Erin, who seemed to feel a little left out, commented, “FEELS LIKE I COULD HAVE BEEN INVITED ON THIS BEAUTIFUL TRIP.”

Instead of extending the invitation, McPheehumorously chided: “@erinfoster mommy and daddy need alone time.”
