Well, today Lainey all but said this poor misguided twit was Drew Barrymore. It makes sense too, because she was in Toronto filming something at the time, hence the first hand reports to Lainey from the film crews there.
Edited to add that the "Unfunny Douche" referred to in the article is most likely none other than Mike Myers who has the reputation around town for being a terribly self-important pain in the neck, who causes all sorts of filming delays with his whimsical "needs" and hires assistants to hold his bottle of water and point the straw in the direction of his mouth when he needs a sip. And yes, he is a local boy from my home town. Ugh.
Fridays are often Lainey's most caustic, so take a gander at today's column if you need a celebrity gossip fix. Just click on "Home" at the top of the Mute Stones item and it'll take you to her current blog.
