Lady Gaga wears odd outfit to sister’s graduation to snub her former school

Lady Gaga put on a very special show this week for the high school that made her life miserable — clearly delivering the message, I’m a star, the rest of you aren’t and you can all go to hell.

Her command performance at her little sister’s graduation at the Convent of the Sacred Heart, on East 91st Street at Fifth Avenue Tuesday, was her way of rubbing the school’s face in the mud, several of her pals told The Post.

The Sacred Heart kids who made her an outcast because of her driving ambition to be star and her parents’ inability to buy her fancy clothing and purses could only watch in wonder as the girl they once knew as Stefani Germanotta wowed another awestruck audience.

She dressed in a beekeeper’s hat and see-through pants and carried a Chinese-takeout-shaped Chanel bag as she strolled the grounds in sky-high platforms that let her stand tall without heels.

Little sister Natali apparently didn’t mind being upstaged by the outrageously dressed diva.

Gaga’s pals said the singer sincerely wanted to support Natali on her big day, but decided to make the occasion a bit more enjoyable by dissing the school she hated.

“Part of going to the graduation in that outfit was her showing the bullies that she has emerged like a swan, she has made something of her life and has found the freedom to express her creativity,” said one of her buddies.

“She’s a star and she’s made it on her own terms.”

Gaga, who never hesitates to spew about the school from which she graduated in 2004, did chat with some teachers who had treated her well.

Before going after her school, she took some practice shots at the church. This week, she released a video, “Alejandro,” in which she mocks Catholic images by wearing a red nun’s habit and swallowing rosary beads.
