Whitney Houston’s daughter Bobbi Kristina Brown is now married to her longtime boyfriend Nick Gordon. A rep for the family confirmed the news that the 20-year-old actress is indeed married to Gordon.

Kristina officially made the announcement on Jan. 9 via her Twitter feed. She posted a picture of her left hand wearing a huge diamond ring, which was joined by Gordon’s hand.

However, the newlyweds’ marriage is raising a few eyebrows since Gordon was raised as Houston’s adoptive son.

Last July, in a Facebook missive, Kristina insisted that her and Gordon was never raised as brother and sister nor was Gordon her adoptive brother.

Nevertheless, Cissy Houston, Kristina’s grandmother, is reportedly not thrilled that her granddaughter is married.

According to TMZ, Cissy is pissed that Kristina and Gordon tied the knot but realized there’s nothing she could do to stop it.

There’s no word on where the couple got married or if Kristina’s father, singer Bobby Brown, was in attendance.

We wish Bobbi Kristina and Nick Gordon many years of martial bliss.
