It was this routine (Wheelchair-mermaid) that pissed off Bette Midler:
You can keep the meat dress and the firecracker tits – mermaid's mine. Dear @ladygaga Ive been doing singing mermaid in a wheelchair since 1980. If you think [it] seems familiar – it's because it is! You can see it on youtube 24/7 – with ME performing it.
What did Gaga say back?
I had no idea that she did that and I'm a huge Bette Midler fan. Maybe we're just cut from the same cloth
(via Access Hollywood). Great answer...
