This is video of Denver Broncos receiver Wes Welker performing as Britney Spears during a pep rally when he was in high school.

Welker attended Heritage Hall High School in Oklahoma City, Oklahoma, before going to college at Texas Tech.

The 32-year old Welker was undrafted out of college, but stuck with the San Diego Chargers in 2004, before moving to the Miami Dolphins (2004-2006), the New England Patriots (2007-2012), and now the Broncos.

A five-time Pro Bowler, Welker has 777 career catches, for 8,647 yards, and 40 touchdowns.
