You know, people keep talking about how Mariah should be featured on Katy Perry's "Birthday," since KP was inspired by 90s Mariah when she wrote the song. I have always said no. BUT.
Today when I was listening to it, I got to the line, "It's time to get out the big, big, big, big balloons" and realized MC would love to be in this video

Katy and MC, side-by-side in low-cut tops. I can see it now
And if gets MC another #1, I won't be mad.
