She is a prolific Twitter user, with 200k followers and over 1300 tweets, mostly pictures of her looking gorgeous while participating in mundane (hanging out with her dog) and exciting ("The Great Wall of China Y'all!") activities. Good for her, I would do the same thing.
She recently posted a photo from her friend's wedding
The most stunning bride @emilyandmeritt celebrating the big day @alifroley @minkakelly and @minkakelly #bestweddingever twitter.com/TheMandyMoore/…Her friend is beautiful but do you know who is the most stunning person there? You, Minka.
How do I know that? BECAUSE YOU WERE CHOSEN AS ESQUIRE MAGAZINE'S SEXIEST WOMAN! LAST YEAR!
I am sure your big boned friend enjoys subtle backhand compliments to remind her who she is standing next to.
And yes, Mandy Moore tweeted it first and Minka re-tweeted it.
