Miley Cyrus says Amanda Bynes' Twitter attacks are "so sad".
The troubled star insulted the 20-year-old singer on the social networking site last night when she called her ugly, but the Can't Be Tamed hitmaker isn't being drawn into a public feud.
Speaking to radio station Hot 95.5, she said, "I won't even entertain that thought. I think it's all so sad and I don't want to add any fuel to that fire. It's so sad to me.
"I was rooting for her comeback until she started attacking me, and I just thought it was hilarious that she mentioned my name the moment I was the worldwide trending topic on Twitter.
"It's just funny the moment you're a trending topic how many people want your name to come out of their mouth, so somehow they can [be associated with you] and maybe they can become a trending topic."
Amanda (27) also insulted rapper Drake on Twitter last week.
Although she deleted the initial tweet she’d written ? "Drake has the ugliest smile, ugly gums, uneven teeth, ugly eyes” ? she later added, "I won't deny calling @drake ugly."
