It's a battle of the divas.

Bette Midler was less than impressed when Lady Gaga rolled onto stage in a wheelchair and dressed as a mermaid in a show last week in Australia.

"I've been doing singing mermaid in a wheelchair since 1980-You can keep the meat dress and the firecracker t--s," Midler tells Gaga in one of several Tweets. "Mermaid's mine."

But soon Midler has a change of heart. In another Tweet, she writes, "Let's drink this over at the Emmys in September. Fabulous mermaids can coexist!"
