It was exactly 30 years ago today, Dec. 8, 1980, that the world lost one of its most influential and important artists—John Lennon. The musician, and one of the founding members of The Beatles, was slain outside of his New York City home by a crazed fan. He was only 40 years old. The world hasn't been the same without him, and many celebrities took to their Twitters to remember the legend. Singer Eric Hutchinson wrote, "R.I.P. John Lennon. 30 years later we still miss you" and rapper Asher Roth reflected, "30 years of remembering John Lennon." Actress Taryn Manning paid tribute in her own way, telling followers, "Today all Beatles!!! We will never forget u John Lennon!!!"
Thankfully, there was a little levity on such a solemn day. Friends and fans of Ian Somerhalder (pictured) wished "The Vampire Diaries" star a very happy birthday as he turns 32. He had so many wishes, in fact, that it started trending! "TVD" executive producer Julie Plec noticed, "The power of fandom. 'birthday ian' is trending. Love it. #happybirthdayian. Love you, @iansomerhalder," as did the birthday boy himself, who wrote, "My birthday is trending? Wow, that's really cool- I feel warm and fuzzy all over. I simply have the BEST fans in the whole damn world."
