America’s most hated mother Casey Anthony has been going out in public regularly – but has put on so much weight that she is not recognisable, it has been claimed. The 26-year-old was found not guilty of the murder of her two-year-old daughter Caylee 10 months ago, despite a string of inconsistencies in her trial defence. Following her dramatic acquittal she went into hiding in South Florida, where she reportedly spent months sitting indoors on the computer and eating to avoid the public  and piling on the pounds. But a source has revealed that this new look – including a ‘puffy face’ – has apparently given her fresh courage as she has been leaving her home regularly.’Casey has been venturing out on a much more frequent basis recently because she is almost unrecognisable,’ a source told RadarOnline.com.
