Madonna Tucks Into Some Pizza...For The First Time Ever!

Madonna tried pizza for the first time during an appearance on The Late show with David Letterman last night.

The 51-year-old singer tucked into a cheese-less slice after telling the host she had never tried the Italian delicacy before.

But it is unlikely that the pizza will affect Madonna's strict diet too much as she only managed to take one bite.
