Miley Cyrus has been criticised for her incorrect use of English grammar in her new song.

Indie rocker, Sufjan Stevens expressed ''concern'' over the 20-year-old singer's inappropriate use of verbs in her latest track, 'Get It Right' featured on her 'Bangerz' album, and decided to address the issue in an open letter written to the star on Monday (14.10.13)

Taking to his Tumblr page, Sufjan wrote: ''Dear Miley. I can't stop listening to #GetItRight (great song, great message, great body), but maybe you need a quick grammar lesson. One particular line causes concern: 'I been laying in this bed all night long.' Miley, technically speaking, you've been LYING, not LAYING, an irregular verb form that should only be used when there's an object.(sic)''

The 'Come On! Feel The Illinoise!' singer also noted that the phrase ''I been laying in this bed'' featured conflicting tenses.

He continued: ''Surely you've heard of Present Perfect Continuous Tense (I HAVE BEEN LYING in this bed all night long [hopefully getting some beauty sleep?]). It's a weird, equivocal, almost purgatorial tense, not quite present, not quite past, not quite here, not quite there.(sic)''

The criticism comes after Miley was slated by Sinead O'Connor, who accused the star of being ''prostituted'' by the music industry due to her raunchy music videos, in an open letter written to the star earlier this month.
