Aaron Carter Who? Ex-GF Keeps Mute On Him...

Madison Parker's either throwing serious shade at her ex or she needs to see a doctor about short-term memory loss.

Aaron Carter's ex-GF was outside Blind Dragon in Weho Friday night when TMX asked her an interesting question about Carter's sexuality that she clearly didn't want to answer.

It seems like there's bad blood brewing between the two since they've split. Aaron before now had said Madison walking out on him was a gut-punch and now she's referring to him as an enemy.

On the bright side - Madison says she loves everyone and prays for the best, and Aaron as also said he's doing great ... in the oral sex department. Recall he recenly broke up woth Madison and came out shortly after as Bi.
