Floyd Mayweather Paid NIcki Minaj 50K Just To Show Up At Daughters Birthday...

Singer Nicki Minaj don't have to sing to make the bank anymoree --  According to sources Floyd Mayweather Jr. paid her (Nicki) $50,000 just to show her face at his daughter's 14th birthday party.

TMZ tells that, Mayweather rented out the entire MGM ballroom in Vegas to celebrate Iyanna Mayweather's birthday last weekend -- and Nicki showed up as a surprise to her.
We're told Nicki stayed for about an hour -- hanging out with Iyanna, taking pictures ... and that's pretty much it.

You'll also recall that Iyanna's birthday party is essentially what set off the brawl between T.I. and Floyd -- after T.I.'s wife Tiny posted a photo of herself with Iyanna. Tiny was an unpaid guest.

Iyanna's pretty spoiled as far as celebrity guests go -- last year, Justin Bieber showed up at her party. Just imagine what her sweet 16 would look like.
