Conor McGregor hangs out with Rihanna backstage in Dublin

It's good to be the king.

Conor McGregor enjoys plenty of perks as the UFC's highest paid athlete. And the Irishman's latest coup was spending some time backstage with superstar singer Rihanna ahead of her concert in Dublin.

McGregor posted a photo with Rihanna on Tuesday night with the caption "an honor to see the pound for pound number 1 female in the game perform tonight! This woman ain't playing!"

The huge show that took place in Dublin's Aviva Stadium actually brought Rihanna to tears, thanks to a crowd that roared all night long while she performed.

In a funny coincidence, UFC strawweight Joanne Calderwood was actually also in attendance at the same show on Tuesday night, although it doesn't appear she got the same backstage access as McGregor.

Now that McGregor has met Rihanna, maybe he'll opt to use one of her songs for his next walk out at UFC 202? No one will know for sure until Aug. 20 when he meets Nate Diaz for a second time.
