Janet Jackson allegedly slapped her niece Paris during an altercation.

The singer and her brothers Randy and Jermaine - siblings of the late Michael Jackson - reportedly went to their mother Katherine Jackson's home to take the 'Thriller' hitmaker's kids Prince Michael, 15, Paris, 14, and 'Blanket', 10, to Arizona to see Katherine.

According to TMZ.com, Paris defied the decisions of her family so Janet slapped her and called her a ''spoiled little b***h''.

But Paris is said to have hit her aunt back and blasted: ''This is our house, not the Jackson family house. Get the f**k out.''

Trent Jackson, one of Michael's cousins, is also said to have become involved in an altercation with Jermaine and Randy and allegedly punched Jermaine in the mouth.

Paris took to her twitter account earlier this week to explain to her followers that she has ''a lot going on''.

She wrote: ''a lot of ppl have been saying that i ''changed'' ... i wanna apologize for the attitude ... there's just a lot going on ... i promise: the ego = gone(: (sic)''
