Lady Gaga rejects $1 million offer to perform at RNC

Lady Gaga once wore a dress made of meat, but apparently even she has her limits. The pop superstar reportedly turned down an offer of $1 million to play at the Republican National Convention. Turns out an independent conservative group - American Action Network - courted Gaga to perform in Tampa, Florida, last summer at an event "honoring women who run for public office." The rejection is probably not much of a surprise, seeing as how Gaga isn't exactly known for her conservative views. But had she taken the offer, she wouldn't be the first celebrity to get a paycheck from a strange ideological bedfellow

Jennifer Lopez reportedly once earned $2 million to sing for a Russian billionaire. Elton John sang at Rush Limbaugh's 2010 wedding, telling "USA Today" they even became friends ("He sends me the loveliest e-mails," the singer said). 50 Cent? You can find him "In Da Club" and and at da bat mitzvah for the daughter of one-time defense contractor David Brooks.

Then there are the indecent proposals - like when Robert Redford offered a million dollars for a night with Demi Moore. Okay, that was a film, but there have been moments with that kind of controversy.

Actress Hillary Swank split with her management team after she appeared at a party for a Chechen leader accused of all kinds of human rights violations. Swank later gave the money to charity. Beyoncé serenaded "All the Single Ladies," and at least one son of Libyan dictator Moammar Gadhafi in 2008. The singer later said she gave all her proceeds - reportedly $1 million - to Haiti earthquake relief. Nelly Furtado and Mariah Carey did similar Gadhafi bashes. In 1996, Michael Jackson did a private party for the Sultan of Brunei. The reported price tag was $16 million.
