Who's There: Marina Acton & 138 Water?

Oh boy, today's Who's There? sends us on a deep, deep dive. First, Kim Kardashian's new "BFF", a woman named Marina Acton who appeared on her Instagram with a single to promote. Who is she? Where did she come from? (The answers will SHOCK YOU!) Plus, something called 138 Water that has all the celebs...accidentally posing for promo shots? Or are they being paid? And what even IS alkaline water anyway? (It's bullshit.) Oh, and the finale of The Bachelor happened and it was fully insane.
