Kristen Stewart and Taylor Lautner

Think Twilight influences pop culture? Check out the 2010 list of the most popular baby names.

The Social Security Administration revealed on the Today show Isabella was the top name for girls last year, while Jacob was the most popular name among boys. Isabella, called Bella for short, is the lead character in the Twilight book series and is portrayed by Kristen Stewart on-screen. While Bella's vampire boyfriend Edward, played by Robert Pattinson, didn't make the cut, Bella's best friend-werewolf Jacob (Taylor Lautner) did. The series' fans are either in the Team Edward or Team Jacob camp, but clearly Team Jacob won in the baby-naming arena.

Another interesting fact to come out of the study is the that the trendiest names — those that have jumped the most in popularity — is a mother and son duo from MTV's reality series Teen Mom. Maci, who first appeared on 16 & Pregnant and was featured in the spin-off Teen Mom, was the top trending name for girls while her son's name, Bentley, topped the trending list for boys.

Other notable observations from the report include that Kellan (Kellan Lutz is an actor in Twilight) is the No. 2 trending boys name, while Knox, the name of one of Angelina Jolie's twins, is No. 3.

While many of the classics like Ava, Emily, Michael and William are included in the Top 10, Joshua dropped off the list for the first time since 1978.
