Lily Allen is busy recording a new album for her music comeback in 2014, but she has one feisty detractor to face as she preps her return in the music biz. American rapper Azealia Banks continues to bash Allen via Twitter after the latter called her a one-hit wonder.

The rapper fired back and tweeted about her recent performance at Glastonbury: One hit, but am certainly NOT a wonder. Just played for 70k at glasto, critics STILL eagerly anticipating my debut. Suck on that hoe!"

The 22-year old rapper, who recently won BET's Best Female Hip Hop Artist award, is also accusing Allen of banking on her to promote her album. ""Lily Allen is promoting the f**k out of Azealia Banks right now," she tweeted.

Both artists are set to release a new record with Banks to deliver her debut album "Broke With Expensive Taste" first. Allen, on the other hand, recently confirmed that she'll be releasing her third studio album on March 2014, the follow-up to 2009's "It's Not Me, It's You".

Banks was supposed to release her debut on September 2012 but had numerous delays since then due to unconfirmed reasons. Before Allen, she was also lashing out against singer Rita Ora whom she called "Rita Oral".

She ended her tweet to Allen with "Ugh, bitch bye" with an unflattering photo of the singer taken by a paparazzi.

Allen temporarily left the music industry in 2011 to focus on her family. The 'Smile' singer gave birth to her second daughter Marnie on January 8.

It's still going to be a long wait for Lily Allen's new album. Meanwhile, let's see whether Azealia Banks can top the album charts once her album is released.
