On Thursday, the star shrugged off the claims, taking to Instagram to share a snap as she joyously enjoyed a topless late night swim.

ShareThe star has her mouth open and her tongue sticking out, as if she is tasting drops of tropical rain falling from the sky.
Although Megan's hands are placed on her chest, they fail to cover her ample assets, with a photo-shopped cross blocking her nipples so as not to violate Instagram's decency rules.

A new ritual: Megan took a cheeky skinny dip on Wednesday with her beau Tiffany
Proving she's more than just a pretty face, Megan captioned her photo with a quote from the late American poet, E. E. Cummings.
'Unbeing dead isn't being alive,' the philosophical quotation read.
The blonde beauty, originally from Western Australia, has recently relocated to Bali with Tiffany - another Bachelor contestant whom she met whilst filming the reality show in 2016.

And it appears the couple are doing their fair share of 'being alive', putting on loved-up displays in bars and on beaches surrounding their new Balinese home-base of Canggu.
Thursday's topless swimming session wasn't the only racy nighttime swim Megan has taken, with the raunchy pool dips becoming something of a new ritual.
On Wednesday, Megan shared a photo with her 142,000 Instagram followers, that showed her in the pool completely nude, as she rested on a floating pool lounger.

First lesbian Bachelor couple: Megan and Tiffany made worldwide headlines, but former cast-mates are now questioning their relationship
'Nudey Swims in Canggu with the DetecTiff [Tiffany Scanlon]! Nearly fell asleep like this thinking about lyyyfffee (sic),' read her caption.
Megan, who is known for writing lengthy, philosophical captions on her Instagram posts, recently used her way with words to pen an essay for Popsugar explaining why she threw away her vibrator, which she nicknamed, 'Andy'.
'Andy was — to be real — just too good on my own. We climbed the summit too quickly every time, and as a result I became lazy with my partner. I wanted less because I was getting it elsewhere,' Megan explained.

However, despite re-locating to Bali with beau Tiffany, two of the couple's former cast-mates have questioned the authenticity of their relationship.
Megan and Tiffany are the first lesbian Bachelor couple anywhere in the world, but on Wednesday, Keria Macguire stated that 'they are faking their relationship', before claiming that the pair's union was nothing more than a 'publicity stunt'.

And on Friday, the Bachelor's third runner-up, Rachael Gouvignon, questioned the couple's claims that they fell in love during their first trip to Bali last June.
'When I caught up with Tiffany when we went skydiving [in October] she told me about a guy she was seeing,' Rachael stated, before adding, 'Megan has also spoken to me about a guy she was seeing ... Maybe their status should be along the lines of an open relationship or bisexual!'
In response to Rachael's claims, Tiffany told Daily Mail Australia that 'for now we are keeping it under wraps' how the relationship turned romantic.
