Madonna: Kissy Kissy with Mercy and David!

Madonna bends down to give kisses to two of her children, Mercy, 5, and David, 4, while on set filming her movie W.E. on the streets of London on Sunday (August 8).

The 51-year-old Material Mom was also joined on set by her daughter Lourdes Leon who rocked a mismatching pair of leggings. After she wrapped her scenes for the day, Madonna rode a bicycle back home!

W.E. also stars British actress Abbie Cornish, who shot scenes for the film in Paris last week.
