Sorry, but that isn't Courtney Love. Not that she couldn't get fat, mind you, but the person in the picture looks nothing like her. Most telling are the lips. If you've seen any recent pictures of Courtney, she's got these freakishly huge Botox-swollen lips (remember when plastic surgery was supposed to make you look better?) The woman in the photo has pretty normal sized lips. Definitley not her.
Beyond that, the rest of her facial structure looks different to me, though granted, that could be distorted by weight gain. However, like I said, someone's lips don't suddenly shrink to half their size, especially not if they're gaining weight.
Besides, everyone knows Courtney drowns her sorrows in drugs, not ice cream.
