Singer Jessie J has pulled out of Robin Thicke's tour to concentrate on recording an American version of her album `Alive`.

The `Price Tag` singer confirmed that she will no longer be supporting the R&B artist in North America in an effort to focus on recording an American version of her second studio album `Alive`.

The star was due to head out on the road in support of the `Blurred Lines` man in February and March, but she took to Twitter Friday to reveal her cancellation, reports contactmusic.com.

"I'm off to the USA to dedicate my time to my heartbeats who have had less of my time than anywhere in the world in the past few years,` she posted.

"No gigs, no music released! So I am going into the studio to write and finish the US version of 'Alive' and hopefully do some small shows and prove to my fans how much I want to be there! Not everything is in my control! But I am making it my goal that my album is released in the USA this year,` she further posted.
