Madonna and Kids are on a Boat

Madonna and her kids - Lourdes Leon, David Banda, Mercy James and Jesus Luz - took a mini-vacation in Italy in celebration of her 51st birthday yesterday.

Jesus Luz may be Madonna's boyfriend, but at 23, he is closer in age to the pop star's children than to her, so he falls in that category. Cute family photo:

The Material Mom celebrated her birthday at the Splendido Hotel in Portofino, Italy, sharing breakfast and alone time with Jesus. What a nice family vacation.

In previous Madonna lover news, Guy Ritchie has recently gone public with Mellany Gandara, while Alex Rodriguez is hitting home runs with Kate Hudson.
