This is LJ Moreno.
Her partner might be Jimmy Alapag, her husband. A basketball player in PH, but not sure if he's currently playing because I haven't watched PBA games after the finals of the last conference.
Re: Anton del Rosario, if the rumor is true that he's part of TARP, someone might be using his twitter account just like what happened to KC Montero before when he was doing Survivor Philippines.
