September's Harper's Bazaar, that's where.
"[The tape] is not real," the Gossip Girl star tells the fashion mag. "So it makes me sort of sad. It's unfortunate that it got carried as far as it did. I definitely understand the nature of people better now and that the mere allegation of something like that could be headline news. People think it's real because somebody says it is."
Moving on, Bazaar also had this totally cool idea to digitally age the 23-year-old to her fifties for the "Fabulous At Any Age" issue, because that's way easier than actually finding real older people. Ahh! Reverse Photoshop, how clever. The results...
So that's what 50 looks like? Leighton even says she's a Botox supporter in the article and she's a famous person, so shouldn't she be looking a little more like Madonna (50) or Demi Moore (46) or Michelle Pfeiffer (51)? Instead they dress her up like a stuffy Upper East Side grandma who lies about cancer in order to manipulate her granddaughter into attending a debutante ball. That kind of stuff really happens, too, you know.
Check out how hot 50 actually is in our Fabulous at 50 gallery.
