You go, girls!
"Next level," the 58-year-old singer captioned the clip of her girls singing and boogying to Nicki's hit which includes lyrics like, "Oh my gosh, look at her butt."
Though most of Madonna's fans thought the cheeky home video of Stella and Esther was nothing short of adorable, some people criticized the mom-of-six for allowing her young daughters to sing such a suggestive song.
"How could you teach little girls that? Growing up in this sex obsessed society is hard enough for girls and women, why force it on them?" one of Madonna's 9.3 million Instagram followers commented on the video. A supporter added, "It's funny. Butts are funny. It's not sexual when kids sing this novelty song."
In another Instagram video, Madonna playfully asks the twins where they learned Nicki's song — but they just keep singing!
The "Like a Prayer" singer previously announced in early February that she adopted Stella and Esther from Africa. "I can officially confirm I have completed the process of adopting twin sisters from Malawi and am overjoyed that they are now part of our family," Madonna said at the time. "I am deeply grateful to all those in Malawi who helped make this possible, and I ask the media please to respect our privacy during this transitional time."
Madonna is additionally a mother to four older children: Lourdes, 20, Rocco, 16, Mercy, 11, and David, also 11.
