Even pop queen Madonna knows to bow down in the presence of Queen B.
The "Material Girl" sang praises to Beyoncé on Instagram after attending her Mrs. Carter show with one of her daughters at Brooklyn's Barclays Center on Thursday.
"Mrs. Carter crushes the BK with her bad ass show!" Madonna captioned one of the pictures she uploaded during the show. "Girls run the world!"
Later, the 55-year-old posted a pic of her of 8-year-old daughter Mercy James getting a big kiss from Beyoncé herself.
"Mercy James gets a big fat one from the Queen. B!" she captioned the pic.
A couple of days after their encounter, Beyoncé revealed Madonna has always been one of her biggest inspirations.
"I felt like I wanted follow in the footsteps of Madonna and be a powerhouse and have my own empire," the 32-year-old singer told fans at special screening of her new music videos in New York City on Saturday.
"And show other women when you get to this point in your career, you don't have to go sign with someone else and share your money and your success, you can do it yourself."
