Rising rapper Angel Haze has once again postponed her European tour dates in order to put the finishing touches on her debut album.

The American hip-hop star was originally scheduled to jet over to the U.K. for a string of gigs in February (13), but she pushed the dates back until May (13).

Now she has taken to her Twitter.com page to explain her decision to call off the concerts once again.

She writes, ''Guys, I've made a tough decision to postpone my Uk & European dates in May. I am totally committed to finishing this record as soon as possible & that means not leaving the studio for now! I promise though when I do come it'll be worth the wait! Thanks for all the support."

Angel Haze, real name Raykeea Wilson, will go through with a planned show at London nightclub Scala on 7 May (13).
