Word is Pat Houston recently filed a restraining order against Nick Gordon. Pat Houston is Whitney Houston's sister-in-law/state executor and she's been none too pleased with Gordon's romantic relationship with Whitney's daughter, Bobbi Kristina. Though never legally adopted by Whitney, Gordon moved in with them when he was 12, and he and Bobbi were treated as brother and sister. Tensions have flared since the two married in January 2014, apparently to the point of Gordon threatening Pat.
