Does 'Money' deserve style points for this or not?
Music stars Justin Bieber and Lil Wayne enter the ring with Floyd Mayweather Jr. before the unbeaten champion takes on Canelo Alvarez at the MGM Grand Garden Arena Saturday in Las Vegas, Nevada.
This fight night outfit is turrrrrble
NBA legend Charles Barkley is seen before Saturday night's title fight between Canelo Alvarez and Floyd Mayweather Jr. But Sir Charles, come on, man! This is Vegas . . . on Saturday night . . . for a megafight. We KNOW you've got a nice suit somewhere.
Don't get jealous, Kobe
Hollywood acting superstar Jack Nicholson is feeling pretty pleased to score Mayweather-Alvarez tickets. Boy, is he lucky, right? The guy may have the best connections on the planet.
Rockin' Fight Night style!
OK, the power of the Internet is pretty incredible . . . and bewildering. Example: Once upon a time, nobody in North America would let this guy anywhere important. Now Psy gets what he wants, from award show appearances, singing for the President and Saturday night taking in the Mayweather fight. Note to self: Get a Youtube account.
Even Denzel is impressed
When you have probably tasted just about everything life has to offer, it's hard to raise an eyebrow at the feats of mere mortals. But check out Denzel Washington: He's pretty jacked by soaking in the sweet science of Floyd Mayweather.
Cap can't hide fact that this is Owen Wilson
When you are a big-time film star, you tire of all the attention at times and just want to enjoy a great fight without being bothered too much. How to disguise thyself? 'Hmm, I know! With this hat, no one will recognize me . . . Genius!'
Poof! I'm here, like Magic! (Get it?)
Basketball Hall of Famer Magic Johnson has a good life, and he's on quite a roll as part owner of the hottest team in baseball, the LA Dodgers. Some would call it magical, but only hack media folks who shower in tired wordplay.
I wear my sunglasses at night
We're not sure why NBA superstar Kevin Garnett was trying to play it so inconspicuous at the Floyd Mayweather Jr.-Canelo Alvarez fight at MGM Grand Garden Arena in Las Vegas Saturday night. Umm, KG: You are a 6-foot-11 string bean with serious ear bling. We see you — and, hey, could you slouch in your seat a bit for the dude behind you?
Sure, Biebs, you are the one, too
Floyd Mayweather Jr., left, poses for post-fight photos with none other than one of his honorary corner stragglers, Justin Bieber. Of course, Bieber is no ordinary member of an entourage. He is, however, very skilled at causing eye rolls among sports fans.
Hey, perk up, it's fight night!
Actor Garry Shandling looks beyond thrilled to be in Vegas for the Mayweather fight. More like, "Been there, done that."
Gettin' Lizzy with it
Actress Lizzy Caplan arrives at the MGM Grand, and smiles for the red-carpet cameras.
Hey, are you Jon Voight?
The Hollywood actor looks like he's got a nice view of the ring action. Wait, let's count how many rows back he's sitting.
What are you looking at?
Cameras catch actor Don Cheadle (right) while chatting with his ringside neighbor at the MGM Grand. Looks like they could be related, but we're not here to discuss Don Cheadle's relatives. That Don Cheadle . . . he can really act. And he was in Ocean's 11 . . . and 12 . . . and 13 . . .
The 'stache champ at fight night
Actor William H. Macy looks perplexed, or mesmerized — one of the two — in the crowd at the MGM Grand. Or perhaps he caught a reflection of his killer mustache. Dream a little dream.
Hey, look! It's Sean Puff Daddy Diddy Combs
Here's a little Diddy who is going wth the bright ensemble at the Mayweather bout.
Put 'em up, Heidi
Model Heidi Klum does her best boxing pose while attending the Mayweather bout. The problem when normally lovely ladies flash these types of "I'm hot, but I'll still kick your butt" facial expressions? They no longer look like lovely ladies.
I'm George Lopez, and I'm damn happy about it!
Actor/comedian George Lopez is showing off his veteran celebrity moves with a classic camera face. "OK, we got the picture, thank for the shot, Mr. Lopez. Umm, I said, 'Thank you,' You can stop smiling now. OK, it's kind of freaking me out. Like, are you trying to read my mind, or fire laserbeams through my brain? Stop creeping me out!" (Editor's note: This was a dramatization)
LL said knock you out!
Here's rapper/actor LL Cool J at the Mayweather-Alvarez fight. Did you know Mr. J is 45 years old? That can't be possible. He could still beat the tar out of most of us.
Fake smile alert!
The accomplished character actor Danny Trejo tries like H-E-double hockey sticks to pull off a simple frown-upside-down. Hmm, that looks painful, kind of like any of our elementary school kids' yearbook shots. Maybe this is why he's usually one of the bad guys.
Ready for her close-up
Apparently actress Emily VanCamp poses for a shot on arrival at the MGM Grand, but quickly made her way in to watch the Mayweather fight.
Pair of aces
Director Jerry Bruckheimer (left) and entertainer Jeff Beacher pose together for a shot in Las Vegas at the Mayweather fight. Somebody get Jerry a comb.
Hey, I'm wacky fun guy!
OK, let's get real and have a behind the curtain moment. So, this is Apolo Ohno at the Mayweather-Alvarez bout in Las Vegas. So, the original caption on the wire services read: "Television personality Apolo Ohno." Television personality? Remember when this guy won like a kajillion Olympic medals?! What's more important? Seriously! Sigh. Well, he's got a chance to be the next Bruce Jenner, I guess.
Trick trivia question: Is actor Ben McKenzie happy or sad Saturday night at the Mayweaher fight in Vegas? Umm, actually, we are asking you, because we have no idea from this picture.
He Tank'ed it!
Singer Tank performs the national anthem before the Floyd Mayweather Jr.-Canelo Alvarez WBC/WBA 154-pound title fight. You know he's singing his heart out. Just look at those neck veins.
