When will they do it?
When should they do it?
What do you want it to sound like?
I think it's the right time for them to work on something for like Katy's 4th album (the 4th album curse can be destroyed if they do a wicked collab that smashes!)
Rihanna's next single should be a Katy collab cause she needs that #1 to help push the album. I don't think she's capable of getting it on her own anymore. She waited too long.
