September 4 is a big day for the Beyhives around the world: Beyoncé just turned 38 yesterday!
And among the millions who greeted Queen B on her very special day was Mariah Carey. The diva took to her Instagram page to celebrate her good friend's birthday with a throwback photo. "Happy birthday 👑🐝 @beyonce!" she simply wrote alongside the snap.
The diva duo has managed to remain tight-knit over the years despite being pitted against each other all the time. FYI, they shared a selfie back in December 2016 as well when Queen Bey attended the Mariah Carey: All I Want For Christmas Is You show with her daughter Blue Ivy in New York City.
