Just days ago, Khloe Kardashian hit out at weight critics on Twitter, defending people for coming in different shapes and sizes.And so what better way to get back at her critics by showing off her toned figure on the red carpet.The reality TV star looked sizzling in a red ‘mullet’ dress as she arrived at the MDA Labor Day Telethon in Los Angeles last night.Although Khloe’s weight has yo-yoed over the years, the 28-year-old certainly looked slimmer than normal as she posed at the CBS Studios.She tweeted yesterday: ‘Holy s**t balls that workout was brutal!!!!! But thank you @Gunnar for pushing me through it.’On Monday, she wrote: ‘Went hard in the gym today with @gunnar I am going to hurt later.’ Daily Mail
