A PLAYBOY playmate has unveiled a bikini that’s so revealing it leaves her looking naked from behind.
Cassandra Sienega, known as CJ Sparxx online, celebrated her 34th birthday poolside with a very racy swimsuit.
The barely-there pink bikini left very little to the imagination as the cam girl and model partied at the Sapphire Pool in Vegas – known for being a topless day club.
The pink two piece covered barely covered her privates and her nipples to the extent that from the back she looked completely naked.
Since posting the tiny pink bikini snap four days ago, Cassandra's post has received almost 40,000 likes from her army of 568K followers.
She captioned the pic: "Celebrated my 34th birthday in style at @thesapphirepool with friends.
“Hands down the best birthday EVER! I'll definitely be back!"
Her fans were sent into a frenzy over the post, as one commented: "We need more outfits like these!"
Another said: "Now this is the most amazing thing I have seen today."
Meanwhile others rallied round to wish the model a happy birthday.
However, others weren't as impressed by the look, as one Instagram users quipped: "Should have just used band aids."

Another agreed adding: “Take it easy on the Internet...sheesh.”
This is not the first swimming costume to cause a stir this summer.
We previously told you about the "skinny dipping" bikini that claims you'll get "no more dodgy tan lines" - but it does give the illusion you're naked.
