Miley Cyrus has launched a Twitter attack on celebrity blogger Perez Hilton, accusing him of always being the first to "try and tear my life apart".

The incident arose from a story Hilton published on his gossip website which speculated that Cyrus was spotted "hanging out" with fellow actor Ed Westwick, fuelling a rumour the young singer and actress was set to end her engagement to actor Liam Hemsworth.

Once the story had broken, Cyrus immediately took to Twitter to condemn the report and offer Hilton a few choice thoughts. Cyrus wrote: 'hope you find love one day but can you not f*** with mine'.

'I've never been with Ed W in my life. I was at the studio last night working on my record and never left with anyone other than my assistant'.

'What happened to your big enlightenment…what happened to your promise to spread love not lies?' the 20 year-old singer asked.

'you're the first one to write about my engagement and my wedding and how happy u r for me and the first to try and tear my life apart. Respect, love, & compassion are mandatory[sic].'

Concluding, Cyrus posted: 'hope this message finds you happy and healthy...feel free to ask me whatever u want but I can't tolerate lies'.

Hilton responded with another story on his website, writing: "we already said the report was odd and had to have been innocent" before adding "Well that must be that, then!"
