Sorry.
No, she's actually a transsexual. She transitioned to a man and is now known as Tatum Channing.
She dated Rosie O'Donnell for a bit, so I'd say she is. https://www.autostraddle.com/tatum-oneal-is-queer-actress-pretty-much-dates-women-now-cause-theyre-amazing-292124/
Yep, she's gay.
ew, I'm straight guy and I would date a dude before Rosie O'Donnell
This means that BOTH the female leads in this were lesbians.
lol
