One of those things that you DON'T want your Dad telling the world.

Parents. Amirite?

Earlier this month, Justin Bieber endured the indignity of having his father proudly tweet about the size of his penis and this week Beyoncé’s dad may have suggested his daughter’s is fibbing about her age.

It just goes to show that you’re never too famous to be embarrassed by your dad.

Four for years, conspiracy theories about Beyoncé’s “real age” have been circulating on the Internet.

The official story is that Queen Bey was born on September 4, 1981, which would make her a sprightly 34-years-old.

But one popular theory (supported by a supposed birth certificate) pegs the singer as 41, claiming she was actually born in 1974.

Adding fuel to the speculative ‘Beyoncé Is Older Than She Says She Is’ fire, the singer’s father and former manager Mathew Knowles described his daughter as the “exact same age” as P!nk and Usher in a radio interview.

Apparently, P!nk was the lead singer of a rival girl group when Destiny’s Child was getting started way back then.

“She was the exact same age as Beyoncé,” Knowles senior told ‘The Breakfast Club’ on New York’s Power 105.1.

“[Then] you had Usher, who was the same age, they were all 14 or 15 years old, living in Atlanta.”

P!nk was born in 1979, making her 36, while Usher was born a year earlier and is 37.

Seriously, the difference between 34 and 36 is pretty negligible — it’s a real possibility the Beyoncé’s padre just misspoke.

Either way, he is clearly proud as punch (and Beyoncé is probably suitably annoyed with him right now.)

So conspiracy theorists, get back in your boxes.
