Mamma meets teach: Bra-flashing Madonna risks embarrassing Rocco by visiting his headmistress on his first day back at London school

Despite overcoming their rocky patch only months ago, Madonna risked embarrassing her 16-year-old son Rocco by turning up on his first day back from summer break - while wearing a sheer blouse on Tuesday. Seemingly oblivious, the Queen of Pop, 58, looked in high spirits as she walked out linking arms with his head teacher after a short meeting. Madonna and her son's principal looked to have become firm friends since they first met during tenser times in April, when the Vogue singer had only just patched up her rocky relationship with her eldest son after he moved to the UK to live with his father. They recently settled their custody battle over son Rocco following nine months of dispute, agreeing that he must continue his education in England while still spending regular time with his mother in America.
