Madonna and daughter Lourdes launched their Material Girl clothing line last night in New York -- but it was her son Rocco who stole the show!
While Madge, Lourdes and "Gossip Girl" star Taylor Momsen showed off the new clothes on the pink carpet, 10-year-old Rocco Ritchie had quite a crowd of his own inside -- where he showed off his breakdancing skills!
Check out all the party pics above -- and the new line here!
