Miley Cyrus has rubbished reports linking her to teen idol Justin Bieber, confirming she's still engaged to actor, Liam Hemsworth.

The former Amanda Bynes' random Twitter outburst, where the [uuid=d0524864-63cf-4633-8c5a-fba7a57b6f9e]actress called Miley "ugly"[/uuid], stating: "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."

Miley added: '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 associate and maybe they can become a trending topic."

Bynes seems to have retracted her comment after hearing Miley's interview, posting on Twitter today (June 13): "Thank you for rooting for me doll! You are one of the prettiest girls! I want my nose to look like yours after my surgeries!"
