Pop star Kelly, 31, and 35-year-old Brandon got engaged in December and it seems they just can't wait to get married.
So much so that their engagement pictures could be mistaken for snaps found inside a wedding album!
Kelly uploaded the photographs to Twitter. The first one shows the former American Idol winner sat on a window seat while wearing a huge ivory bridal gown.
She is reading an old book in the picture and is surrounded by many more hardbacks on the shelves around her.
Alongside the picture, Kelly tweeted: "Ok, just saw my engagement shoot pics & I have to share one!!! :)"
Kelly has since tweeted another gorgeous picture, this time taken in a brick archway leading to lush gardens.
Wearing a demure and classic bridal dress with intricate silver beading across the shoulders, Kelly is nestling in to Brandon has he tenderly holds her from behind.
Kelly said: "Okay... One more from our engagement shoot ha!"
Brandon - who is the son of Kelly's manager - presented his now-fiancée with a whopping yellow canary diamond ring when he popped the question. They are thought to be getting married on 20 October this year.
