First it was her lips… but has Kylie now opted for BREAST implants?

She came clean earlier this year, admitting – after much speculation – that she has indeed had lip enhancement injections.

But following on from her appearance in Florida last night, rumour is now abound that Kylie Jenner has also recently opted to have breast implants inserted.

Wearing a head-turning low-cut black dress, with which she did not wear a bra, the 17-year-old certainly seemed to be sporting a remarkably generous bust.

Indeed, the look is very different to the one displayed by the reality TV star late last year.

However, Kylie herself has been eager to shake off any gossip relating to her changing body shape.

Taking to Snapchat, Ms Jenner told her fans: "To whoever thinks I have breast implants, there's a whole lot of tape holding these up."

She then pulls down her dress to display the tape – as well as a generous amount of cleavage.

In March, when rumour first began to swirl, Dr Steve Fallek told HollywoodLife.com that Kylie "clearly looks like she’s had implants placed".

Dr Anthony Youn agreed, telling the same website: "Wow! Kylie’s looking more and more like Kim every day. Her breasts do appear to have been enhanced, going from a B to a D cup in size."

And a well-placed source around the same time told RadarOnline.com that momager Kris Jenner, 59, had signed off on the enhancement. 

Kylie's eldest sister, Kourtney Kardashian, has always been open about her own breast surgery, admitting that she had the procedure done when she was 22.  

Although it is widely thought that Kim Kardashian has also boosted her bust with implants, she has never publicly acknowledged doing so.
