Things didn't go according to plan.

Kendrick Lamar is getting slammed for apparently lip syncing his way through his halftime performance at the College Football Playoff National Championship Game between the Alabama Crimson Tide and the Georgia Bulldogs, and we've gotta say he wasn't very convincing.

In fact, people are praising Donald Trump, who was also in attendance, for attempting to actually sing along to the National Anthem. Although, viewers were quick to point out the POTUS didn't appear to know the actual words to the patriotic tune. You'd think he'd brush up on the verses before embarrassing himself on a national stage!

Perhaps Kendrick should have called Britney Spears for some tips, and Trump should have done his homework!
