I'm a huge Bettie Page fan! So when I heard from Pabs that there was a droid in Revenge of the Sith that was modelled after Bettie, I couldn't believe it.

Until I read the Databank entry on it:
George Lucas' directives described the droid as the automated equivalent of Bettie Page, and the droid design quickly earned the nickname "Bettybot." Though the scenes of Bail's offices were ultimately cut from the film, the droid was nonetheless designed and modeled as a CG character. Renamed the BD-3000 droid, it can be seen briefly during the Senate landing platform scenes and the Galaxies Opera House scene.

Here Betty Bot is in all her glory.
