Australian model-turned-actress Rachael Taylor - best known Stateside for her role as signals analystÂ Maggie in Transformers - is joining Grey's Anatomy for a multi-episode arc, sources confirm to me exclusively.
Taylor's character is still being conceived-she's not scheduled to debut until midseason-but a Grey's insider confirms that she will be playing a (surprise!) doctor.
In addition to Transformers, Taylor also starred opposite Joshua Jackson in the 2008 horror flick Shutter.
Season 7 of Grey's gets under way on Sept. 23.
