Unfortunately, sparring with Mario Lopez doesn't win fights for Oscar De La Hoya.
Several days prior to his major match-up Saturday in Las Vegas against Floyd Mayweather â€" which resulted in De La Hoya's losing in a split decision â€" the boxer held a friendly round with Lopez, a Golden Boy himself in the eyes of Karina Smirnoff.
The former Dancing with the Stars favorite was far from the only celebrity on hand for this big fight over the weekend.
Also on hand at the MGM Grand Las Vegas for the bout were: Tobey Maguire, Jay Z, Leonardo DiCaprio, Matthew McConaughey, Charlie Sheen, Eddie Murphy, Helen Mirren, Denzel Washington, Jack Nicholson, Eva Longoria, Jeremy Piven, Kevin Connolly, Michael Jordan, Michael J. Fox, Diddy, Sacha Baron Cohen, Will Farrell and Jermaine Dupri.
Couples such Jennifer Lopez and Marc Anthony, and Jim Carrey and Jenny McCarthy were also in the house.
Meanwhile, One person who was very happy with Mayweather's victory was his close pal, 50 Cent. The hip-hop star bet $1 million on the winner and walked out of the arena saying "easy money."
After the fight, hip-hop royalty was on display â€" and even put on a mini-concert as the DJ spun their music â€" at Venetian's Tao Nightclub. Hanging in the VIP booth: Jay Z, Usher (without fiancee, Tameka Foster), Diddy, 50 Cent, Jermaine Dupri, Young Jeezy, Nelly and Ashanti. Baron Cohen showed up later, but kept a hat low over his eyes.
"There's been a lot of negativity given to hip hop lately, but I want you to look at this group," Diddy said. "There is nothing but love up here."
From theer, we assume, the mogul went home and showed more love to Kim Porter and their twin baby girls.
