Help! How do I remove this metal earring from this 1990s reproduction Barbie?

It feels like the earrings are hooked together inside her head and I have no idea what the neck peg looks like on this doll. I just bought her for my daughter (11 yr old) for Valentine’s Day. She was new in crushed box with crumbled elastics. I’m surprised the metal earrings have not discolored the head yet.
