Coca-Cola turns 125 years old this weekend, and the soft drink company is celebrating its birthday like any of us would -- by throwing a party with lots of great music.

The Coca-Cola 125th Anniversary Celebration Concert featuring Kelly Clarkson, Ne-Yo and others will stream live at www.coca-cola.com/125 this Saturday, May 7, from noon to 4PM EST. The ubiquitous Ryan Seacrest will host the festivities from the company's hometown of Atlanta.

Clarkson, the inaugural 'American Idol' champ, has been scoring hits for nearly a decade now, while R&B singer-songwriter Ne-Yo has released three platinum albums in the last five years.

In addition to these Grammy-winning artists, the concert will feature "Unwritten" singer Natasha Bedingfield, British indie rock band One Night Only and acclaimed rapper K'NAAN.
