Katy Perry Rejects American Idol

With seemingly every artist having been connected to the open American Idol Season 12 judging spots over the last couple weeks, we can cross one name off the list:

Katy Perry.

Sources tell TMZ the singer turned down an offer from the Fox competition this week. A $20 million offer, that is.

Why would Perry reject such a massive payday? Insiders cite her busy schedule and also her belief that it simply wouldn't have been the proper career decision.

So, who does this leave as a possible partner for Mariah Carey? Who doesn't it leave?!?

Everyone from Lenny Kravitz to Keith Urban to Kanye West to Nicki Minaj have been considered for the gig, with the latter rapper seemingly on the verge of signing a deal.

Britney Spears, Mars Curiosity Tweet About Space

Britney Spears is apparently is on top of current events.

The singer, or whatever intern she has running her Twitter, was tweeting at NASA's Mars Curiosity rover earlier this week, and it was pretty funny!

The singer wrote, "So @MarsCuriosity... does Mars look the same as it did in 2000?" She included a link to her video for "Oops!...I Did It Again."

Britney "visited" Mars in that video ... playing out an interplanetary love story and setting an intergalactic camel toe record with her red latex catsuit.

The best part? Mars Curiosity responded!

From the red planet (or at least the NASA Jet Propulsion Laboratory in Pasadena, Calif.), the Cur-zizzle took a break from collecting samples to post.
