Brandon Blackstock and Kelly Clarkson
's wait for a ring
"I'M ENGAGED!!!!!" she announced Saturday on Twitter
. "I wanted y'all to know!! Happiest night of my life last night! I am so lucky and am with the greatest man ever."
pop star, 30, and freshly minted fiancé Brandon Blackstock, a Nashville-based talent manager, began dating
a year ago. Blackstock is the son of Clarkson's manager, Narvel Blackstock, who is married to Reba McEntire.
Earlier this year Clarkson joked that she was so happy it was "ruining my creativity" and that she was now "writing all this happy" stuff.
The only thing that had been missing, she said in November, was the wedding bling, and even then she was sure it would be arriving. As for her ceremony plans, she told Ellen DeGeneres
: "We will totally, probably elope."
