Martha Stewart sorry for ‘insensitive’ homeless Halloween costume

American lifestyle guru Martha Stewart has apologised for an “insensitive and not funny” Halloween costume after she appeared to dress up as a homeless person.

“It’s hard to admit when you’ve really screwed up,” the billionaire, 85, wrote on Instagram after she deleted a photo of herself in ripped jeans, a torn jumper and a dirtied face.

Stewart also held a clipboard that read “I Am Hungry Help Me!!” Social media users quickly slammed her as out of touch.
