Yet another ex is in Johnny Depp's corner!
The letter, dated Friday but only revealed now says in part:
Feast your ears on this greatness!!
And we have a feeling people will be dancing to it all day long! Oh, and they'll probably be putting on their best British Britney accents to match the pop princess herself.
Basically, everyone is going to be loving all over this HOT song!
