Before the championship bout, Floyd stepped out with the heavyweight rhymer.

Last week was a tough one for Lil Wayne. He suffered another seizure and lost his endorsement deal with Pepsi due to backlash over controversial lyrics. But Saturday night (May 4) he was all blinged-out smiles in Las Vegas as he strolled out with WBC welterweight champion Floyd Mayweather minutes before the boxer stepped in the ring to fight contender Robert Guerrero.

Fittingly for the rebellious rapper who refuses to let setbacks bring him down and for Mayweather, who would eventually win the fight and continue his career-long undefeated streak, Wayne performed "No Worries." The cut was a Hot R&B/Hip-Hop Songs top 10 single and is from his latest album, "I Am Not a Human Being II." Watch the performance below:
