Azalea breaks new US chart record

Australian rapper Iggy Azalea has broken a new chart record.

Her hit Fancy has become Billboard's longest-leading No.1 by a female rapper after six weeks at the top.

She surpassed Lil' Kim's previous record of five weeks for 2001's Lady Marmalade collaboration.

In May, she also broke a record held by the Beatles since 1964 by scoring the top two spots with her first two chart entries.

"Pretty good way to start July!" Azalea wrote on Instagram.

"Lots of motivation to continue to work hard."

Azalea also used the occasion to address rumours of a fued with fellow female rapper Nicki Minaj.

Minaj sparked suggestions of a feud after rallying for rapper's to write their own lyrics during a rambling acceptance speech for Best Female Hip-Hop Artist at the BET Awards.

This was interpreted as a slight against Azalea, who is rumoured to have used ghost writers on some of her tracks.

But on Thursday, the Change Your Life singer was having none of it.

"The general explosion of pettiness online in the last few days is hard to ignore and honestly, lame," she wrote on Thursday.

"I'm unbothered by anything that 'happened' at the BET Awards."

"(I) just feel worn out by everyone trying to make me have wars with people all the time."

Meanwhile, Minaj has also since shot down speculation of a riff.

"I've congratulated Iggy on the success of Fancy, publicly," she tweeted.

"The media puts words in my mouth."

Azalea's other Billboard hit - Problem, her collaboration with Ariana Grande - still holds the No.2 spot.
