She read a mean tweet not "tweets" since you seem to be such a stickler for details. Also "and was great then", What is that even referring to? You're also using far too many commas not to mention far too many words as people do not want to read your monotonous moans. Get a diary "Love".
Its not nice when people are randomly mean over the net is it? Think next time.
Love, she read mean tweets, didn't write them, and was great then, go check out the video and then talk. Also, you're using too many -est and most- in just one sentence, there are too many people, and 'celebs', to be talking so big just for just one of them. Like one, love one, but don't judge the rest.
As far as I'm concerned, Kristen can tweet anything she likes - she's the hottest, most desirable celeb on the planet!
