Carrie Underwood has a big reason to celebrate this week. The singer has officially landed her 16th No. 1 single this week with her hit song 'Blown Away.' The tune is the second single release from her fourth studio album of the same name.

Underwood just couldn't wait to share the good news of reaching the top of the charts with her fans. "Just got the news that 'Blown Away' is #1!" she tweeted Sunday afternoon. "So happy! So many thanks to Country radio and my wonderful fans! It's going to be a great day!"

The writing team behind the smash is the same two writers who penned another one of Underwood's career tunes, 'Before He Cheats' -- Chris Tompkins and Josh Kear. The two recently spent time at the top of the charts with Luke Bryan's latest No. 1 hit, 'Drunk on You,' which the two wrote with Rodney Clawson.

The 'Good Girl' hitmaker's latest chart-topper is also the title of her latest tour, the Blown Away Tour, which is currently criss-crossing the United States. The trek, which will continue through the end of the year, also features up-and-coming sensation Hunter Hayes. Click here for a full list of dates where the tour will be stopping.
