Ryan Seacrest is officially over the hill! Today, America’s favorite host turns 40 years old and we are wishing him a very happy birthday. Seacrest burst onto our screens in 2002 when he began hosting American Idol, added radio expert to his resumé in 2004 when he started taping his own show On Air with Ryan Seacrest, and soon followed by taking on hosting duties for Dick Clark’s New Year’s Rockin’ Eve with Ryan Seacrest in 2005.

This year, Seacrest will lead the traditional countdown to midnight from Times Square while Fergie hosts the Billboard Hollywood Party from the West Coast. The extravaganza will be one of the biggest celebrations of the year, with more than 38 live musical performances including numbers by Taylor Swift, Iggy Azalea, One Direction, Meghan Trainor, Charli XCX, Elton John, Idina Menzel, Florida Georgia Line, and more. This is definitely one show not to be missed, and we can't wait to ring in 2015!

Make sure you tune in to Dick Clark’s New Year’s Rockin’ Eve with Ryan Seacrest live on Dec. 31 at 8 p.m. ET on ABC.
