Carrie Underwood's 34th birthday may be hard to top!
She got a phone call from the legendary Loretta Lynn who serenaded her with "Happy Birthday," got some amazing gifts from friends and family, and got the ULTIMATE birthday cake!
Carrie is a HUGE Walking Dead fan, so imagine how excited she was when her bff gave her this Walking Dead themed cake!
Ellen Degeneres sent Carrie a special video for her birthday!
