Madonna is sporting a bruise on her cheek after being shoved by paparazzi at London's Heathrow airport over the weekend -- while she was holding her adopted son.
The star returned to her home in London from New York City where she had spent the week promoting her newest children's book, "Too Good to Be True," along with her U.S. TV concert special.
A source close to the singer tells People magazine, "She had the baby in her arms when it happened.
"When she landed in London, there was a lot of pushing and shoving. She was jostled around. She got hit in the paparazzi's commotion."
Madonna's 1-year-old son David, whom she is in the process of adopting from Malawi, was not hurt in the scuffle.
