UFC legend Joanna Jedrzejczyk has sent fans into overdrive with her holiday snaps - as they speculate on whether or not she has had a boob job.

The 31-year-old Polish fighter was letting her hair down on the beach in Koh Nang Yuan, a small island off Thailand, when she treated her 1.2million Instagram followers to some new photos.

And the red bikini she wore prompted some to think the flyweight star had boosted her appearance.

One comment alongside a beach selfie read: "Loved the old you but sure as hell am not complaining about the nice 'upgrade'."

Another joked: "Breast of luck to you in the future Joanna!"

A fellow user wrote: "Someone as tough as you are should not be that beautiful!"

Jedrzecyzk recently revealed she turned down the chance to return to the Octagon in March.

She told WezloFM: "I received a fight offer for March, but I turned it down.

"For now on, I just want to rest a bit, have a nice time with my family and eat well."

Jedrezejcyzk has not fought since she lost to Valentina Shevchenko at UFC 231 for the vacant women's flyweight title.

And prior to that she suffered back to back title fight defeats to Rose Namajunas, ending her eight-fight unbeaten streak.
