Billboard has confirmed that Kelly Clarkson has become the very first American Idol contestant to earn "100 chart-toppers, counting all national and domestic music charts (current, recurrent and catalog)."

Country sensation Carrie Underwood is hot on Clarkson's heels with a total of 83 No.1s and Chris Daughtry, who performs under the stage name Daughtry, is in third place with 40 chart-topping hits. 

Vocal powerhouse Adam Lambert, who has also been touring with iconic rock band Queen over the past few years alongside making waves with his own career, has 10 No.1s, Philip Phillips has accumulated 20, and Jordin Sparks has 7 to her name. 

Clarkson, meanwhile, recently admitted that once she has her baby she won't be adding to her family because pregnancy is 'too rough' on her: "Oh, no, we are done. Oh good Lord, yes, I can't be pregnant again. This will be our number four total, so we're good... Honestly, the first one was really rough, and I was like, 'Oh, it can't happen again,' and no, it happened, like, way worse this time."
