50 Cent Says He’d Love to Fight Floyd Mayweather, But Floyd’s Too Small

50 Cent says there’s one guy he’d love to punch in the face — Floyd Mayweather — but he doesn’t think Floyd would ever agree to throw down.

Everyone knows the backstory … 50 and Floyd used to be super tight — but they’ve had SEVERAL falling outs over the years and it seems like the relationship is still fractured.

So, when 50 appeared on V-103’s “The Morning Culture” show Friday and was asked who he’d like to square off against in a celebrity boxing match, it wasn’t too shocking when the rapper dropped Floyd’s name.

“I’d fight Floyd,” 50 Cent said … adding, “I don’t think I can make weight though.”

50 pointed out Floyd usually fights around 150 lbs — and the 45-year-old rapper says there’s just no way he can slim down to match Floyd’s weight.

50 claims the last time he dropped to 150, “I looked like a homeless person.”

Instead, 50 says he thinks he could fight at 180 lbs … which is closer in weight to Floyd’s next opponent, Logan Paul, who fights around 190 lbs.

Let’s get serious … everyone would watch Floyd vs. 50 — especially since 50 has real boxing training under his belt and reportedly stays in solid shape.

Remember, the two used to be super tight — 50 famously walked Floyd to ring when he fought Oscar De La Hoya back in the day.

But they’ve since beefed about everything from Floyd’s reading skills to 50’s financial situation … and the hatchet appears to be far from buried.
