The Amanda Bynes Twitter tirade continued when the troubled actress attacked Miley Cyrus and called her "ugly" while the "We Can't Stop" singer's name was a trending topic on the site Wednesday.
Bynes, a former Nickelodean child star who has been on a downward spiral of arrests and controversy over the last year, tweeted a curt message to the rising pop singer, frankly stating, "Ur ugly @mileycyrus."
To further drive her point home, the 27-year-old actress also attached a photo of Cyrus at the recent Billboard Music Awards.
Cyrus, a retired Disney star who has been making media rounds to promote her new single and upcoming album, chose to take a mature approach by ignoring Bynes' childlike social-media attack.
However, the former "Hannah Montana" actress did acknowledge the Tweet during a radio interview with Hot 99.5 in Washington, D.C. when the host asked if a battle between the former child stars would ensue.
"I won't even entertain that thought," said Cyrus. "I think it's all so sad, that I don't want to add any fuel to that fire. Because it's really so sad to me."
Cyrus, who is also engaged to hottie Liam Hemsworth, added, "I just thought it was so hilarious that she mentioned my name the moment I was a worldwide trending topic on Twitter... The moment you're a trending topic, it's funny how many people want your name to come out of their mouth."
After throwing Cyrus major shade, Bynes tweeted her aspirations to produce an album and go on tour.
"I'm so looking forward to recording my album and going on tour! I can't wait to see you all at my concerts!" she wrote.
She also remained indignant about her posts by adding, "This is my twitter. I say whatever I want. Thanks!"
