She gave an interview on an Internet podcast and said they never dated, but didn't say the reason might be because he's actually gay. I thought the interviewer was going to ask her that but he didn't.

I think that they were good friends. I have heard several interviews where she and Kim Fields talked about TC being very close to both of them.
I know one thing.that TC can sing!!!

I doubt the hate part. TC Carson was just featured on an episode of Erika and Kim C's web series, The BFF Chronicles.
"I'm not boring you am I?
No my doctor says I need to air out the back of my throat every 5 minutes."

I've heard its an open secret TC is possibly gay. Regardless they had amazing chemistry. Rumors were that they hated each other and didn't speak offset.
Hope to know the truth one day.

Not, sure but they have the same birthday, lol.
I'd catch a grenade for ya, throw my hand on a blade for ya
