Madonna reportedly declared her toyboy lover Jesus Luz as “love of her life” at her recent birthday bash in Italy.

The Queen of Pop, who turned 51 on August 16, allegedly dedicated her speech to the 22-year-old Brazilian model before running across the room to plant a passionate kiss on his lips.

"He's the love of my life. He has been so strong around me. I can't thank him enough," Contactmusic quoted her as apparently saying.

The couple was spotted taking a break as they hopped on a luxury yacht with the singer’s children - Lourdes, 12, Rocco, eight, Mercy, four, and David, three.

An onlooker said: "She and Jesus looked madly in love and it was great to see her looking so happy. They just looked like any normal family enjoying a holiday together."
