"Huh? You can't mention that Tito is dating Jenna?" - From: tenchu
Actually, no, they can't. Aside from being in poor taste to bring up Tito's current personal life, they couldn't mention anything else without his or her permission. Simple as that.
Dana obviously has more respect for Tito than to do that to him.
I believe that the show was meant to create a new soap opera in MMA and generate business. You think Tito would agree to it unless he had an ulterior motive? Hell no, Tito is working WITH Dana on something - don't know what yet, but it's coming, rest assured.
