Clothes from the star's "The Pamela Collection", which were supposed to have arrived in stores in the autumn of 2004, seem to be nowhere now, reports Ireland Online.
The blonde star had announced in 2003 the release of the clothing line that would include jeans, t-shirts, sweaters, jewellery, lingerie and fragrance.
"I wanna know where it is. I mean, I keep on trying to figure out what's going on. It's a mystery," admits Anderson, the star of new comedy "Stacked".
"Everyone's a brand these days, everyone has a clothing line and I'm just focused on my show, focused on my kids... well, hopefully we'll find it. I don't even know where it is."
