Twilight fans name Twi-hard babies
Twilight fans have been inspired to name their children after characters Edward Cullen, Bella Swann and Jacob Black.
Cullen, the surname of the hit film's vampire hero, played by heartthrob Robert Pattinson, was the fastest rising boy's name for 2009, according to the US Social Security Administration.
Cullen also rose almost 300 places from 2008 to 485 on the New York Times list - the biggest increase in any boy's name.
Isabella, the full name of Kristen Stewart's character, Bella, has replaced Emma as the most popular baby name for girls in 2009 and the abbreviated Bella is up to the 58th spot.
Jacob, the name of Twilight werewolf played by Taylor Lautner, is the number one boy's name today for the 11th year.
According to Yahoo! in 2009, Twilight was the number two most searched for term on the internet for the entire year, while vampire baby names and Twilight baby name searches have spiked enormously in the last three years.
Yahoo!'s lifestyle trends expert Elycia Rubin said: "There's a huge trend in Yahoo! Searches with people searching for character names not stars' names. They're not so much searching for Robert Pattinson or Kristen Stewart or Taylor Lautner, they are, but even more so we are seeing a great trend in users searching for the characters, Bella, Jacob, Edward, Alice and so on."
