No topic is off limits for Rihanna!

While appearing on The Ellen DeGeneres Show, the talk show host asked RiRi how "her" was doing. Of course, she was referring to the singer's private parts

Last November when Rihanna sat down with Ellen, RiRi told Ellen that since her dating life wasn't going so well, it wasn't good for "her" ... pointing down to her privates. At least both ladies have a great sense of humor!

The "We Found A Love" singer also opened up about kids. She told Ellen, "Yes, eventually. I mean, absolutely."
