Ashlee Simpson might just be one of our best-dressed pregnant celebrities of 2008! She's told us that she's happy to be wearing maternity clothes, but that doesn't mean she's not looking fantastic. Dressed in a striped trapeze tank and booties, she got a treatment at Senna nail salon in Beverly Hills this weekend. Ashlee's donated those trousers to Pete Wentz, and she's still knee-deep in skinny jeans anyway!

I wonder if Pete was wearing them here.
