I went to Britney Spears’ concert in Las Vegas, and during the concert she said something about how she once had a bet with a friend of hers that the highest mountain in the world was Mount Kilimanjaro. She said she had a major blonde moment when her friend responded that it was Mount Everest that was the highest mountain. She said Mount Kilimanjaro was only #37 on the top 50 list of mountains. She also said that now that friend calls her “37” every time he sees her as a joke. She also mentioned that she could’ve sworn she saw it on ‘Jeopardy’, but that her selective attention span was to blame for the mishap. She also joked that everyone has those moments when they say something stupid and go, “Why the hell did I say that?” It was cute.
