We don't necessarily expect our pop stars to be in the loop with current events, so we were pleasantly surprised to see Britney Spears tweeting at the Mars Curiosity rover.
On Aug. 14, the 30-year-old pop star tweeted:
"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."
If you recall, Britney "visited" Mars 12 years ago, playing out an interplanetary love story in that video, while wearing her now-iconic red latex catsuit.
The Mars Curiosity -- which is NASA's latest mission to the Red Planet, has been roving the ground since Aug. 5 and has been taking photos and videos of the planet -- playfully responded to one of Earth's most famous singers:
Too cute, but their adorable exchange also has us feeling really old -- we can't believe it's been 12 years since Britney released "Oops!...I Did It Again."
