No. Two is more than enough, a commercial pop star needs to stand on their own two feet as Gaga said and I agree. As a Gaga fan I don't want her doing a lot of collaborations with other commercial pop stars.
The Telephone music video was fantastic, but I think another collab would be overkill. I don't really want Gaga to collaborate with different artists for a while, but if she does, I would hope she doesn't repeat a previous collaboration.
I had a friend in college who I wasn't so close with but he had a lot of friends, they went to a few gaga concerts together and stuff. When lotus came out he told them he liked it and bought it and they beat him up and stopped talking to him.
before you quote me think, is your comment about marina too harsh? and realize that i will report you if you shade her
