Beyoncé got a big surprise when her husband, Jay-Z, walked out on stage while she was performing in Philadelphia on Thursday night.
The singer was in the middle of introducing her dancers and band when he snuck up behind her, grabbing her around the waist and planting a kiss on her cheek. As the crowd went wild, he rushed off stage.
Beyoncé posted the pics of the sweet moment on her tumblr blog, and it's clear by the expression on her face that it wasn't a pre-planned appearance by her husband.
Jay-Z and the couple's daughter, Blue Ivy, have been accompanying Beyoncé on some of the dates of her Mrs. Carter World Tour.
