The sex of the baby isn't even known yet, but Mischa Barton hopes the child born to her best friend, Nicole Richie, will be a future rock star.

PR inside reports that Barton presented Richie with several T-shirts, featuring legendary rock bands like the Rolling Stones and AC/DC. 

"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," says Barton.

Although rumors are rife that Richie and boyfriend, Joel Madden are expecting a boy, Barton says she deliberately avoided gender-specific colors because no one knows the baby's sex.
