Kelly Clarkson Reveals Her Birthday Plans With Husband Brandon Blackstock

— -- Happy birthday, Kelly Clarkson!

The original "American Idol" turns 33 today -- but only her husband, Brandon Blackstock, knows how she'll be celebrating.

Asked by a fan on Twitter how she'll mark her special day, Clarkson tweeted, "Brandon is surprising me with birthday getaway so we will see :)."

Clarkson married Blackstock in 2013. Their daughter, River, was born last year.

Luckily for the singer, her husband is a man prone to romantic gestures. Last July, he gave her a 10-acre field of sunflowers, her favorite blossom. On her birthday two years ago, he gave her a bouquet of sunflowers and a red velvet cake that he made for her himself.

However, Clarkson has more than just her birthday surprise to look forward to. She also revealed on Twitter that the video for her next single, the Sia-penned "Invincible," is "coming soon," writing, "we are about to shoot [it]."
