The Fancy star sparked speculation she had undergone filler injections after she posted a picture to her account showing her sporting noticeably fuller lips.

Fans even compared Iggy to reality TV star Kylie Jenner, who recently admitted having temporary lip fillers to give herself a fuller smile, but the rapper is adamant she has not had any more cosmetic surgery on her face and puts the new look down to make-up.

"I get it they (my lips) look bigger in that one picture, it's just the make-up. There's a million pics after that look regular (sic), it's a reach... They just need gossip to post over Xmas and it's a slow news week at this time of year," she tweets.

Iggy goes on to joke, "Wait a min (sic) guys. I thought we had already confirmed, I had an entire face transplant like 8 months ago..."

The rapper has been open about her previous dabbles with cosmetic surgery, revealing she underwent a breast augmentation last year (14), and in August (15), she confirmed speculation she also had a nose job, saying, "I'm not denying it. Denying it is lame."

However, Iggy is adamant the one thing she will not be changing is her hair colour, as she is determined to stay a blonde.

"I've been blonde my whole life with no intention of changing..." she tweets.
