Jillian Bynes Twitter Fued With Sister Amanda Bynes?

Amanda Bynes has been using the social media platform twitter to attack numerous celebrities, insulting their looks and careers with offensive tweets. However, in a seemingly more malicious turn, Bynes is tweeting insults about her own sister, Jillian Bynes. Jillian is Amanda's older sister at 30 years old.

In one tweet, the former Nickelodeon star and current rap prospect Amanda Bynes said, "My Sister Jillian Has An Ugly Face Don't Worry Drake."

She references musician Drake in many other tweets, calling him ugly and more specifically insulting his looks.

"Drake has the ugliest smile, ugly gums uneven teeth ugly eyes," she tweeted in just one of her attacks toward the musician.

Amanda followed up on her insults to her sister, tweeting, "Check Out [Every] Photo Of My Sister Jillian, She's Not Pretty!"

Thus far, Jillian has not responded to her sister's aggressive and mean tweets.

In the past, the two Bynes girls seemed to have a good relationship. Jillian even appeared several times on her little sister's Nickelodeon hit "The Amanda Show" back in the early 2000s.

Jillian acted in a community theater production in her youth, and though Amanda was too young to be involved, she memorized all of her older sister's lines, according to IMBD.com. What happened to the once convivial and loving relationship between the sisters? It seems nothing is safe in the wrath of Amanda's Twitter.

The sisters have an older brother, Tommy Bynes, and thus far the eldest Bynes sibling is safe from his little sisters social media rants.
