Mischa said: "I got her a bunch of rocker tees for the baby, with different types of logos of rock bands on them. And she loved them! They were so unique. I just loved them!
"She is going to have the most fabulously dressed baby, I am sure, because she is so stylish herself."
Despite Nicole's father, singer Lionel Richie, claiming 'The Simple Life' star and fiancé Joel Madden are expecting a boy, Mischa insists the couple do not know the sex of their unborn child.
She added to People magazine: "She actually doesn't know what she is having. She wants it to be a surprise."
