Now that Angelina Jolie and Brad Pitt’s baby brood is growing into a gang of kids, their taste of music is evolving — causing some problems in the family home. Star magazine reports that at least one chart-topping artist has been banned completely after 8-year-old Pax and 7-year-old Zahara started singing her dirty lyrics.

The dirty ditty in question? Rihanna’s “Birthday Cake”. If you’re not familiar, a sampling of the lyrics reads:

It’s not even my birthday
But he wanna lick the icing off
I know you want it in the worst way
Can’t wait to blow my candles out
He want that cake, cake, cake…(etc.)
Ooh baby I like it, it’s so excited
Don’t try to hide it
I’mma make you my bitch

“Pax was singing the lyrics to ‘Birthday Cake’ and laughing hysterically at the curse words,” a source told the gossip publication. In reaction, the actress has reportedly put parental blocks on music streaming sites and is now monitoring more closely what her kids are listening to.

The source added, “Angie grew up pretty fast, and she wants her kids to avoid that same mistake.”
