"The reason I don't say anything is because I don't know, and even when I know something, it changes the next hour," Harrison tells TVGuide.com. "I decided to keep my mouth shut until I know what the hell is going on."
Brad, 38, proposed to the 25-year-old Southern belle at the end of Season 15, and although they remained together during the After the Final Rose special, Emily made it clear she wasn't moving to Brad's city of Austin any time soon. Rumors of a breakup have been swirling for months, and People magazine has reported that Emily was seen without her engagement ring.
"They really have battled through this. I want them more than anything to be happy, they're good people," Harrison says.
So will fans of the ABC show find out if the latest couple is no more?
"A part of me wants to give the fans what they deserve, it is [Brad and Emily's] private life, yes, but it's a part of the gig, " Harrison adds. "They'll let everyone know when it's for sure [but] I don't even know if they know yet."
