This Is the Worst Idea for a Reunion

So Rihanna is going to be the musical guest when Eli Manning hosts Saturday Night Live a week from tomorrow, right.

Which is fine an dandy – I enjoy RiRi.

But I am not liking what I just heard from someone in the know: Rihanna is considering performing her latest (oh-so-randy) hit “Birthday Cake,” which features her ex Chris Brown (ya know...the guy who beat her up), on the show with Chris Brown.

WTF, girl! Do not do that.

Don’t even think to take the stage with that guy’s hologram.
