2015 isn't over yet, but it certainly is an important year for Carrie Underwood!
The 32-year-old Oklahoma native and Grammy-winning country singer is celebrating four major milestones in her life. Among them: The birth of her and husband Mike Fisher's first child, son Isaiah Michael Fisher, who was born on Feb. 27.
She's also remembering the 10-year anniversary of a career-related event that changed her life forever. Her American Idol victory.
"This was just a very, like, milestone year for me, in so many ways," Underwood told E! News. "There's so much in life and in my career it's just milestones for me."
Her new album Storyteller also marks a milestone for Underwood. The record is set for release this Friday and features the single "Smoke Break," which dropped in August, with a sexy music video to boot.
