Tito Ortiz: Jenna And I Haven't Split!

Tito says he and Jenna are still together, although he spoke obtusely about a "big argument" recently. As for why Jenna wasn't wearing her wedding ring yesterday, Tito says it doesn't matter -- they're still a unit.

We asked Tito about several tips we got ... that Jenna allegedly threw some of his expensive watches in the ocean after a New Year's Eve fight and he had to hire a scuba diver to retrieve the items. Tito says the real story is that his kids like throwing things in the harbor -- which they did with his expensive glasses ... and that's what the scuba guy was looking for.
