On Sunday, rapper Blueface was caught on video physically assaulting his mother and his sister, as he physically threw them out of his home.

Last night Blueface's mother spoke out for the first time since being physically attacked by her own son.

And the rapper's mother claims that her son "changed" ever since he's become famous. She also strongly suggested that Blueface may be on some type of drugs or narcotic - that is effecting his action.

Here's her full statement:

Luckily for the Los Angeles rapper, neither his mother or sister are cooperating with police, who are trying to charge the rapper with assault.

Here is the graphic video showing the rapper putting hands on his mother and sister, and throwing them out of his Los Angeles mansion.

Blueface, real name Johnathan Michael Porter, achieved international fame last year when his song Thotiana went viral. The song eventually hit #1 on the Billboard 100.

Blueface also spoke to TMZ and said this:

Blueface wants to get his side of the story out as to why he kicked his mom and sister out of his house -- so he's posted more footage of the altercation with an explanation.

The "Thotiana" rapper threw up multiple clips of what appears to be surveillance video from inside his home, which was the site of chaos last weekend ... as the family drama played out on Instagram Live. But, he says this new video tells the full story of what was going down, 

In Blueface's clips, you can see 2 women causing a ruckus in his crib -- shouting at him from downstairs with a small child in their company as well. 

The MC captioned his post, writing ... "Sense [sic] they wanna go viral so bad this the real story my mom got tired of my broke ass sister free loading at her house so she brought her to mine an I wasn’t going for it I already got her an apartment guess that wasn’t enough she want my car she want me to buy her a car off the lot an some more stuff."

He adds that he once had to live out of his car and struggle to get to where he's at now, and then goes on to blame his fans for turning against him before they had the full context of the fight.
