PHOENIX (AP) — A 3-year-old Arizona's boy celebration of his adoption is a hit on social media.

Dezhianna "Dae" Brown's Twitter post of photos of her adoptive brother Michael had over 55,000 retweets and nearly 140,000 likes by Friday morning.

The little boy is now a member of a family living in Phoenix's Peoria suburb.

He gives a fist pump in one photo taken at court. Another has him posing with Brown and another adoptive sister.

Brown says Michael was "super-shy" when placed with family as a foster child in early 2015 but has since opened up and bonded with her family.

Brown told The Associated Press in an interview Thursday that her mother, Tara Montgomery, adopted Michael on Tuesday.

Court spokesman Vincent Funari said he could not discuss a child dependency case.
