Yes, that is Don King, he whose hair mimics the Pontiff's headgear, front row at the papal audience yesterday. King gave B16 a handwritten note asking for prayers (including for President Bush --ain't that nice?) and the gift of a title belt. So I guess Benedict is a heavyweight champion now.
King manages an Italian boxer whose brother is a priest, which is how this was arranged. This is nice too:
Before arriving in Rome, King toured Messi's hometown, Bergamo. During the visit to the northern Italian city, King began a fundraising campaign to restore the city's church of St. Mary Major, which includes frescoed paintings on the walls of a pre existing church buried underneath.
