Staff Writer @christamarie123Katy Perry and Madonna seem to be pairing up...but for what? Earlier today, Perry's Instagram followers were treated to a picture of the songstress laying on the floor reaching out to another woman's leg: The caption reads: "Mmmmm my baby's got a secret..." If you are a fan of Madonna, you know that this is a lyric from her single "Secret" from 1994. The plot thickens as just a little bit later, Madonna's Instagram followers were shown a photo of her kneeling on the same carpet, with another woman's legs, presumably Perry's, in the background: The caption reads: "V magazine got me like…..………Kneel down for what??????? @vmagazine This week. #artforfreedom #unapologeticbitch." This is not the first time that Madonna has used the hashtag #unapologeticbitch, however. She has used it several times, which fans of the singer are speculating means that she is getting a new single ready. Though Katy Perry is currently on tour in Europe, she has been performing a mash-up of her song "International Smile" and Madonna's song, "Vogue." Could this be all it means? Probably not. Could these two megastars be planning a mash-up of their own in the form of a collaboration? That seems a bit more likely, though neither camp has confirmed. Keep Up With PopWrapped On The Web!
