The top baby names list for 2010 was announced this morning on "Today" by the Social Security Administration, and many of the chart-toppers come as no surprise. However, some names that made the list might have been inspired by unexpected trendsetters, including some of the stars of MTV's reality show "Teen Mom."

Surprisingly, the name Joshua didn't make the cut for the first time since 1978.

In addition to the most popular names, the SSA also revealed a list of trending baby names that show the biggest spikes in popularity. Leading the trending girls name: Maci, the moniker of "Teen Mom" star Maci Bookout. Her son's name, Bentley, ranked as number one for the biggest trending name for boys.

Also noteworthy: Knox, one of Angelina Jolie and Brad Pitt's twins, and "Twilight" name Kellen appear on the trending list, too.
