Perhaps offering some light on the situation, Tamina appeared at last night’s SmackDown live event in Montgomery, Alabama, coming to the rescue of AJ along with Alicia Fox.

Natalya def. AJ, with special referee Aksana. After the match AJ complains about Natalya holding the ropes for extra leverage in the sharpshooter and gets double teamed by Aksana and Natalya for her troubles. Alicia Fox and Tamina make the save. (Source)
So it looks as though the second generation Diva is indeed the face in the situation — despite being the one that attacked Natalya.
