Britney Spears has revealed why she did not invite her brother, Bryan Spears, to her wedding.

The “Lucky” singer called out Bryan on Tuesday in a since-deleted lengthy Instagram post, and shed some light on her anger toward him.

She began her post joking about the revelries on her wedding day, saying that despite having a great time, she never really had anything to sip at the event.

“I didn’t drink one sip of alcohol!!!,” she wrote. “I can’t drink a lot… true story—the 13 years of being in the conservatorship I was drug tested at least 3 times a week.”

“I don’t even really like alcohol… meanwhile I heard that my dad would go to bars every night… and my brother had this shrimp with Jack and coke every night in Vegas after my show and even sometimes before!!!,” she continued.

She went on to criticize her brother, saying he would not even let her sip his cocktails when they’d meet after her shows. The singer also suggested that Bryan seemed to enjoy power-tripping her, just like her dad.

“My question is this WHY????? Let’s talk about it… is it the powerful feeling dad got my whole life and literally making me feel like absolutely nothing?” she wrote.

Britney also called out her brother over a podcast interview he had made previously, in which he insulted his sister when asked why their family wouldn’t just let her be.

“Your podcast interview was so SPECIAL!!! I know you and the family had no bad intentions at all whatsoever taking all those years away when I wanted to honestly just be a respected individual with a glass of red wine. But like you said in your interview when asked by that incredibly kind man ‘Why doesn’t your family just let her be?’ Your response was, ‘She can’t even make a dinner reservation,’” she wrote.

Bryan's girlfriend, Amber Lynn Conklin, had earlier claimed the latter was unable to attend Britney’s wedding due to another family commitment. In her and Bryan’s joint Instagram account, she posted a photo of Bryan and his 11-year-old daughter with ex Graciella Sanchez, and noted in the comments that he was not able to attend Britney’s wedding because it was his daughter’s graduation.

The Instagram account has been deactivated as of this writing.

However, toward the end of her post, Britney denied her brother and his partner’s earlier statement, writing, “You were never invited to my wedding. ... You hurt me and you know it.”

“I know you’re my blood and yes blood runs deep but no family of mine would do what you guys did to me. GO F*** YOURSELF Bryan—F*** you,” she concluded her post.
