Iggy Azalea returns to Twitter to respond to Erykah Badu's rap diss

Iggy Azalea has responded to soul star Erykah Badu's recent criticism about her place in rap music, calling the argument "exhausting".

The On & On hitmaker hit headlines on Sunday (30Nov15) during her stint as the host of the 2015 Soul Train Awards, when she called out the Fancy rapper during her opening monologue, insisting the music Iggy makes is "definitely not rap".

It's not the first time a hip-hop star has taken aim at the Australian, who has had to defend herself from remarks made by Snoop Dogg and Azealia Banks, and on Tuesday (01Dec15), after a month-long break from social media, Iggy returned to Twitter to respond to Erykah's diss.

She wrote, "Hi guys I know its been a while. We are days from 2016, but I came online today and saw its still cool to try and discredit my 2014 accomplishments. LOL, f**king hell. Seems exhausting."

Iggy went on to update her fans on her plans for her next record, explaining she's still "trying to restructure some things", as she continues to live in the U.S., but is signed to Def Jam records in the UK.

Iggy, who is engaged to basketball star Nick Young, also revealed in her Twitter missive that she is "heartbroken" after finding out one of her pet horses might have Lyme disease.

"I hope he will get better, but its already been 3 months without riding him... I'll let you guys know if i get any updates, but if not... see you next year! enjoy the rest of 2015."
