Theodora Richards has left IMG to join her sister Alexandra on Wilhelmina’s roster.

IMG plays home to all the rock star kids: Lou Doillon, Julia Roitfeld, Liv Tyler, Elettra Rossellini, Daisy Lowe (yes, we use the term rock star liberally), but the gorgeous blond Richards sisters, daughters of Rolling Stone Keith and model Patti Hansen, are now holding down the Wilhelmina fort.

Theo’s starred in ads for Tommy Hilfiger and Roberto Cavalli for H&M, but maybe, with a package deal for the two sisters, they’ll get to join their dad in the realm of luxury advertising.

A family portrait for LV? Sounds do-able.

Wilhelmina announced this morning that they’re going public.

When private companies decide to go public, it usually means that they need to raise some cash, either because they have some nagging debts, or because they just want to have the capital to expand.

We’re curious to see what, if anything, comes from this. Wilhelmina hasn’t really been relevant in terms of fashion models for a while, at least not in comparison to major players like IMG and Women. Though WIlhelmina helped launch the career of Lauren Hutton, their roster of clients right now is headlined by Fergie, Brandy, and Natasha Bedingfield.

Maybe they’re raising money to steal away some of the girls on Model.com’s Top 50 - because, as of right now, Wilhelmina is entirely absent.
