What would happen if a black hole met a 1-solar-mass star made of antimatter?

The antimatter star would meet the same fate as a matter star. It would spiral into the event horizon of the black hole and get ripped apart by tidal forces. To understand why, consider the phrase coined by astrophysicist John Weeler: "A black hole has no hair." Wheeler tells us a black hole's contents are not primarily matter.
