Tito Ortiz: Jenna And I Haven't Split!

Tito Ortiz tells TMZ ... the swirl of rumors that he and Jenna Jameson have separated are untrue ... right down to the story that Jenna allegedly threw his expensive watches in the ocean.

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.

Life at the beach.
