The country star will only refer to the big 3-0 as "the first anniversary of my 29th birthday"

Carrie Underwood is singing the blues about her birthday.

“It’s actually not my birthday,” the country star, who turned 30 on Sunday, tells CMT Radio. “It is the first anniversary of my 29th birthday. So it’s more of an anniversary celebration than a birthday. I mean, I’ll still, like, blow out candles and stuff because I want my wish, but it’s not a birthday.”

Her hubby, Mike Fisher, on the other hand, loves all three decades of her in a sweet Tweet.

“30 years ago today my best friend was born,” he wrote. “Happy birthday @carrieunderwood.”

Underwood responded with an equally kind message that said, “Aww Love you more than anything.”

For her 29th, Fisher, 32, threw Underwood a surprise ’80s-themed party. There’s no word yet on what she did this year.
