Uh-oh Kim Kardashian! As Amber Rose strips off to a tiny bikini, is she trying to impress her ex Kanye West?

Let the battle of the bums commence!

In the red corner, it’s Kim Kardashian. In the blue, Amber Rose.

Amber has posted a string of jaw-dropping shots with her ample booty on display, which are sure to rile her nemisis Kim.

The latest shots of Amber on a jet-ski in a thong bikini have gone everywhere which will no doubt rub Kim up the wrong way, proving Mrs W‘s not the only one who can break the internet after driving the world wild with her oiled derriere last year.

Perhaps the Keeping Up with the Kardashians star has every reason to be cautious. Newly-single Amber could be sending a sign out to Kim who she believed stole Kanye from under her nose after supposedly sending him pictures of her when Amber was dating him.

Just recently Amber has made the most of her ass-ets by posting a video of her shaking what her mama gave her with fellow ample-bottied star Black Chyna. While many of Amber‘s fans have lapped it up, others would prefer her to keep her antics to a minimal.

But Amber has hit back at critics telling her to put more clothes back on the only way she knows how to… by showing off even more skin.

The 31-year-old model put her fabulous behind on full display in a thong bikini as she rode off in a jet ski in Miami, Florida on Monday, the same day she told internet trolls to ‘Kiss my a**!’. She left little to the imagination as she sat on top of the small watercraft in the teeny tiny pink swimwear.

The ex of rappers Kanye West and Wiz Khalifa, also hit back at a few of her critics as she posted a caption along with a picture of herself posing provocatively against a tree.

‘Kiss my MILFY a** b*****!’ Amber wrote to the online critics who had told her: ‘Omg ur a Mother put some clothes on’.

Sounds like there’s no stopping her.

Let the battle of the booties begin, eh Kim!
