Only two-and-a-half weeks remain until the long-anticipated bout between Floyd Mayweather Jr. and Manny Pacquiao. Despite all the jokes about the matchup being the best of 2008, it's still being promoted as the "Fight of the Century" and the public is responding as such.

Ticket prices are so high that celebrities don't even have first grabs on them, having to pay a hefty sum for the best seats -- though some companies are willing to pay for them if stars are willing to shill for brands at the match, according to TMZ.

Maybe the best way to go about the whole "getting an impossible ticket" thing is to appeal to each fighter. There are many celebrities who know them personally. Some have been in their corners in the past. Others have stopped by the boxers' training sessions in the lead-up to the fight.

So, which celebrities are on Team Mayweather and Team Pacquiao? And what does that say about their chances?

In Floyd Mayweather's Corner...

Justin Bieber

The Biebs has a long, annoying history with Money May. The two met in 2011 -- after Bieber had interest in an app Mayweather was invested in -- and he's been present in-ring for Mayweather's matches with Miguel Cotto, Canelo Alvarez and Marcos Maidana, making him Mayweather's biggest celebrity fan.

Bieber's grown cozy enough with Mayweather that he felt fine crashing a Mayweather-Pacquiao presser in late March dressed like a cowboy in the Matrix. And Pac just figured it was some random dude walking on stage.

Who knows if Biebs will be with Mayweather in May. He is in the middle of a very public image rehab project and Mayweather isn't the most wholesome (read: possibly monstrous) human being.

50 Cent

OK, so these two guys might not actually be buddies, but Fitty will definitely be rooting for Mayweather to remain undefeated in a few weeks. Back in August, in the heat of the Ice Bucket Challenge Days, 50 Cent challenged Mayweather to read one page from a Harry Potter book, in exchange for a generous charity donation.

But 50 will be rooting for Mayweather against Pacquiao regardless, considering the rapper is betting $1.6 million on a Mayweather win. That kind of coin will make you like anyone, fast.

David Hasselhoff

You just don't hassle the Hoff.

The Night Rider himself attended Mayweather's final press appearance before the bout and broke the match down on For the Win.

Hasselhoff said he would try to make it over to one of Pacquiao's training sessions, but he hasn't been yet. That makes his presence at Mayweather's training a tacit endorsement of the fighter.

The Hoff has spoken.

In Manny Pacquiao's Corner...

Jeremy Lin

One recent visitor to the Pacquiao camp was the LA Lakers guard.

Unfortunately, Lin's Lakers just finished their season as the second worst team in the Western Conference. That's not the kind of mojo you want heading into the biggest fight of your life.

Stephen Curry

Pacman needs a winner on his side. The likely NBA Most Valuable Player (if the voters are smart and/or right) hasn't gone to see Pacquiao train, but Curry has been supporting the fighter.

Pac, an admitted fan of Curry, plays and coaches in the Philippine Basketball Association and took his b-ball skills to a Warriors practice. Meanwhile, Curry showed him some pre-match love with a signed jersey a few weeks ago.

But that isn't all. Curry also met and took a photo with Pacquiao's sons.

Ronda Rousey

If Manny needs even more champs on his side, this will do it. Rousey is one of the most dominant fighters in the world. And she took some time to go to Pacquiao's training and show him some support.

Rousey also threw her support behind Pacquiao in a recent episode of First Take and called him a "friend."

"I really believe if Manny doesn't jump in and if he's just really relentless pressure and uses all of his speed, I think he's going to give Floyd an extremely hard time."

It's probably a good sign that Pacman is backed by an actual fighter -- a UFC champion at that -- and not guys who got beat up by the dude who played Legolas.

We'll see how it all plays out May 2.
