APOLLONIA LLEWELLYN has shown off her underboob in a racy Instagram video.
The boxing ring girl left little to the imagination as she joked "the bikinis are getting smaller" in the caption.
She posed in a skimpy silver and pink bikini in her latest social media upload.
Apollonia pouted and smouldered for the camera whilst standing in a swimming pool.
Her fans were left swooning in the comments section after being treated to another racy video.
One follower commented: "Gorgeous girl."

The model is no stranger to showing off her photoshoots and travels around the world.
One recent post saw her dubbed the "hottest babe in the world" after she shared a "natural" swimming pool selfie.
Apollonia also shared a cheeky throwback snap of herself sticking her tongue out in a separate upload.
Fans had earlier this week been treated to another racy snap of the ring girl in a leather corset as she put on a busty display for her followers.
