Whitney Houston's sister-in-law has obtained a restraining order against the new husband of the late singer's daughter Bobbi Kristina Brown after alleging he made threats against her.

Pat Houston claims Nick Gordon also posted photos of guns on Twitter.com earlier this month (Mar14), directly after an alleged fight at a family function.

Now he has been ordered to stay away from the I Will Always Love you star's former manager and confidante, who is also the executor of her sister-in-law's estate.

Gordon received the legal paperwork on Monday (24Mar14).

Brown and Gordon announced they were married in January (14).
