Andrea Bocelli Performs at Kourtney Kardashian and Travis Barker's Wedding

One of the best voices in the world helped out with one of the first dances that the two of them did together. Bocelli is a singer.

The Barkers were treated to a performance of "Can't Help Falling in Love" by the Italian tenor. Matteo was invited to perform and guests were treated to him. Two people performed music.

They shared a long kiss, in true Kravis fashion, while he belted out the tune.

Guests at the wedding were given a private boat ride to the venue, as we reported. The couple rented out Castello Brown, a 13th-century military lookout.

A newly married couple in Italy celebrated their wedding day over the course of 4 days. Our sources say only a limited number of family and close friends were invited to attend, including Mark Hoppus and the bandmates.

There will be another party for a larger group to celebrate with the new couple.
