Cinco De Mayo And Kim Kardashian's 'Death Threats' From Bieber Fans In Today's Tweet Dreams

Feliz Cinco de Mayo, Tweet Dreamers! Celebrities were most certainly celebrating May 5th in full force, including Miranda Lambert who tweeted, "Happy Cinco De Mayo!!! I feel like having nachos!" Elsewhere, Ashton Kutcher pondered how he'd celebrate the holiday, posting, "i wonder if United Airlines will serve margaritas inflight in honor of cinco de mayo...."

Someone who wasn't having the most joyous Cinco De Mayo was Kim Kardashian, who was learning the dangers of being within a few feet of Justin Bieber! A few days ago the riot-inducing Justin joked he and Kim were an item, but his fans were none too amused. Kim posted last night, "Seriously Biebs! @JustinBieber I'm getting death threats from your fans! This is unBeliebable!!!" as Justin put out the fire today, telling his very devoted female followers, "ladies calm down. @kimkardashian is a friend. a very sexy friend but a friend. no need 4 threats. Let's all be friends and hang out often ;)"
