TV star Katharine McPhee — who’s reportedly dating pop composer David Foster — accidentally crashed a weekend wedding in Cabo San Lucas, Mexico, and was kicked out by the bride.

McPhee was with a close pal, producer Hilary Shor — whose credits include “Lee Daniels’ The Butler” and “Children of Men.”

Shor posted their snarky commentary about the incident in a series of publicly available Instagram stories on her feed, calling the poor bride who denied them entry to her nuptials a “loser.”

One video seen by Page Six and captioned “Bride Bitch” shows McPhee in her room snottily noting, “What bride does her own wedding security? If you’re doing your own security, you have a problem.”

A second clip’s titled “dead bride #rude bride,” and a third’s called “loser bride bouncer” — in which Shor quips to McPhee off-camera, “She could have had a Page Six, New York Post [article] of us coming and dancing the night away . . . By the way, I was ready to rock ’n’ roll.”

McPhee is shown in bed giggling and chiming in: “I was ready to show some serious moves.”

McPhee also says in a video on the vacation: “Hi everyone, it’s late-night shenanigans.”

Shor also posted captions of their wedding crash fail: “That bride voted for Trump I can feel it,” and “Rise above the rude bride. She should be so lucky to dance with me, I got moves.”

McPhee, 33, is currently dating Foster, 68.

Shor made her Instagram account private after we reached out, and even though we’d already seen the videos, told us: “It was tongue-in-cheek. Katherine did not say anything like that. Do not run that, it’s not true.”

Well, they did want a Page Six item, didn’t they?
