Perry was part of Blue Origin's all-female spaceflight on April 14. Mariah Carey fans are loving a video of her learning about Katy Perry's trip to space — almost four months after the fact. The singer was asked in an interview if she would like to go to space as Perry did, but Carey expressed some disbelief: "Did she go to space?"

It would seem Mariah Carey is just a bit spacey, since the diva extraordinaire missed some pretty big news recently in the worlds of both pop culture and science.
