Granny with the rack

I speak almost no Spanish but look in on Univision and Telemundo because they feature so many hot babes in revealing attire. Yesterday I chanced upon this show and saw an older woman (hard to say how old but she looked in her mid-fifties) wearing a very low-cut dress and showing off some impressive cleavage. She was on today's episode, too. Who is she, and does she always show off "the girls"?
