Michael Jackson's children have been to watch the Unity tour.

The 'Thriller' singer's three children - Prince Michael, 15, Paris, 14, and 10-year-old Prince Michael II, known as Blanket - have been to watch the late King of Pop's brothers perform in Saratoga, California.

The children's grandmother, Katherine, accompanied them to watch Marlon, Tito, Jackie and Jermaine Jackson on stage and put on a show of unity after the bizarre family feud which exploded last week.

Katherine lost custody of her grandchildren when she appeared to have gone ''missing'' for a week, but was allegedly resting under doctor's orders in Arizona.

Custody was granted to Michael's nephew TJ, the son of Tito Jackson, in her absence and she will now share guardianship of Prince Michael, Paris and Blanket since her return to their family home in Calabasses, California.

Prince Michael has shared his cryptic opinion about the Jackson family feud on twitter, posting:

''As long as I can remember my dad repeatedly warned me of certain people and their ways.

''Although I am happy my grandma was returned, after speaking with her I realise how misguided and how badly she was lied to. I'm really angry and hurt.''
