Lady Gaga Addresses Madge Feud, Katy Perry Comparisons, and Weight Gain in Twitter Tirade

Lady Gaga is doing what she wants — so you'd best look out!

The 27-year-old's latest single, "Do What U Want" featuring R. Kelly, was released at midnight, so in the hours leading up to the big drop, she got a few things off her chest while also promoting the song.

In a series of tweets posted late Sunday night, the songstress took on some recent criticism against her, posting the charge first, then her own response to each one:

Over the weekend, Gaga also released the cover art for "Do What U Want" and didn't hold back there either. The provocative photo features the back of a blonde – whom we can only assume is Gaga — wearing nothing but a G-string.

Yep, there's no doubt about it — she's doing what she wants.
