Don't mention it. But if you want some unsolicited advice? Don't approach him. Tell her what I said. Or hell, I'll tell her for you if you want. But let her tell him if she wants to. It's her choice what she believes. Whatever he's told her isn't your problem. All you can do is present the truth and let her do with it what she wants to.
The last time you tried to confront a romantic rival? Well, that's how my mother ended up dead.
