Mayweather, Pacquiao meet and chat

Both fighters are big basketball fans who attend games regularly. 

The two fighters chatted to each other briefly before exchanging telephone numbers.

When all negotiations are finally agreed upon and signed, the two welterweight champions are expected to face each other on May 2 at MGM Grand Garden in Las Vegas.

Pacquiao's manager, Michael Koncz, declined to reveal what was said between the fighters, labelling it "a private conversation."
