No.
Beyoncé helped a then struggling up and coming popstar launch to heights she wouldn't have reached otherwise.
She is the reason for all of Gaga's success.
Beyonces section does provide a nice interlude in a somewhat dull song. That said though, Gaga was on a huge streak at the time and had just released arguably her most impactful single. So I think the follow up to bad romance would have been a hit regardless.
