Who's There: Hassan Jameel & Acacia Brinley?

This week on Who's There? it's true, we're catering to YOU. First, more on Rihanna's new hook-up, Hassan Jameel, and whyyyyy that explains her 'feud' with Naomi Campbell. Then, who remains a Who post-Pretty Little Liars? Is it...all of them? Some of them? A newly-mommy'd mommy vlogger named Acacia Brinley who does some of the most impressive Instagram #spon we've ever seen. James Packer gets himself into some trouble with the Israel government? (And Mariah has no idea what we're talking about.) Ed Westwick got a new girlfriend and her name SOUNDS familiar? Anyone? Bueller? Teresa Giudice Vagina Monologues?
