Kelly Clarkson has announced that she plans to marry her boyfriend Brandon Blackstock.

The singer announced the news on Twitter saying: “I’m engaged!!!!! I wanted y’all to know!! Happiest night of my life last night! I am so lucky and with the greatest man ever : )”

Clarkson, 30, had previously hinted at being in love with 35-year-old Blackstock so much that the relationship was “killing her creativity.”

Speaking last month, she said: "Our priorities kind of shift and you become happier, and all that stuff," she told The AP.

"It's probably my best accomplishment because I think, for me, especially, I just didn't think it would happen.

"It's like one of those cheesy love songs that didn't exist, but it does, so that's cool."
