Beyonce's sister reprimands Instagram user for calling her son 'ugly'

Singer and celebrity DJ Solange Knowles took a rude Instagram user to task on Friday (30Oct15) after the follower called her son "ugly".

Beyonce's little sister shared a picture of her 11-year-old boy Julez dressed up for Halloween as a young LL Cool J, wearing the rap veteran's signature Adidas tracksuit and sneakers with a woolly Kangol bucket hat, and oversized headphones hanging around his neck.

"Young cool J too cool for ghost and goblins," the proud mom captioned the snap.

The post attracted a slew of compliments from fans, but one female follower wasn't so kind.

"So cute but at the same time he ugly (sic)," the critic wrote.

The message caught Solange's eye and she wasted no time in reprimanding the young woman for trying to "spread ugliness".

"Jussst (sic) as I thought it was safe to share pictures again, a young'n (sic) like you decides to use her time to spread ugliness," the 29 year old wrote. "I don't fault you, I can only imagine why you would feel the need to say such things, but thanks again for being a reminder that out of all the love and wonderful energy shared, that when I open up a space for an innocent beautiful being like my boy to be criticized and judged, that I WILL most likely respond, and that he receives enough love and celebration at home that it's just not worth it to go down this road (blast you in public).

"I hope this really resonates with you and you make better decisions in the future towards how you use your words towards innocent children..."

"This could have truly gone south if I was in the wrong mood," Solange added.

Julez is the singer's only son with her ex-husband, her teenage sweetheart Daniel Smith. She is now married to music video director Alan Ferguson, who she wed in her adopted home of New Orleans, Louisiana last year (Nov14).
