Possibilities range from a limited tour in smaller venues to a full-scale stadium tour involving other artists, with 50 Cent, Eminem, and Wiz Khalifa being named.

Lady Gaga is currently under fire for a food-related issue--but this time it's not anything like a dress made of meat. The superstar angered scores of fans earlier this week with a tweet many interpreted as dangerously supportive of eating disorders.

"Just killed back to back spin classes. Eating a salad dreaming of a cheeseburger #PopSingersDontEat #IWasBornThisWay," Gaga's Twitter account read on Tuesday.Lady Gaga

The Twittersphere response was swift and negative, with users taking particular offense to the "don't eat" hashtag. Many tweeted such comments as "disgusted," "lost respect," "stupid," and "so wrong" in regards to the remark.

Etheridge and MichaelsTwenty grand a month or so probably sounds like a nice payout to most average divorcees out there. However, Melissa Etheridge's ex-partner, Tammy Lynn Michaels, isn't one of them. The 37-year-old former actress has filed documents claiming she cannot survive on the $23,000 Etheridge is granting her monthly in child and spousal support.

So, how much money does Michaels need, exactly? Well, according to the paperwork, she explains she became accustomed to a monthly budget of $128,000 during her nearly 9-year relationship with the iconic rocker.

Michaels also noted that she "has limited income and virtually no savings," while Etheridge "has extensive resources at her disposal and a tremendous earning capacity."

Madonna has given Yahoo! Music an exclusive video from her Ultra Music Fest surprise appearance in Miami! The pop queen came out on stage last week before Swedish DJ Avicii's set to do a little call and response with the astonished audience. Avicii kicked off the set with his remix of Madonna's single "Girl Gone Wild". You can imagine how much the audience was flipping out, and now you can watch just how massive the whole experience was!

Along with her surprise appearances, Madonna's taking over the internet! Just a week into signing up for a Twitter account for the first time ever, the pop queen has already held two Twitter chats with fans, plus celebrity friends and well-wishers. Last night's chat that Madge did from the floor of her living room included names like Anderson Cooper, Britney Spears, Katy Perry and a particularly long chat with former neighbor Lionel Richie ("the other ritchie in [her] life...").
