She recently hinted her high-profile romance with superstar Mexican-American boxer Ryan Garcia was over - just days after it was first announced.

And on Tuesday, Mikaela Testa, 25, appeared to be showing him what he was missing by sharing a gallery bikini snaps to Instagram.

One photo captured Mikaela flaunting her ample assets in a barely-there fruit-patterned bikini.

Mikaela's hair was styled perfectly straight around her shoulders and she gazed seductively into the camera lens.

Another showed Mikaela rocking her best angles in her two-piece while sunbathing by a pool as she revealed she was soon going to be going on an overseas trip.

'Last day of sun before Japan tomorrow,' she wrote next to the snap.

Last week, Mikaela took to Instagram to post a series of pulse-racing shower selfies - but fans were quick to question her new relationship with Garcia, 25.

'Your relationship with that schizo boxer lasted so long,' mocked one follower in the comments.

She fired back, 'Please show him some respect. No one has any idea of the ups and downs and what has been going on in my personal life. 

She concluded the brief statement, 'Everyone deserves respect, please don't talk about him that way'.

Last month, Garcia announced he and Mikaela were an item in a gushing social media post.

'Look this is my baby, MY QUEEN BELIEVE THAT! Stop judging her, is she perfect? No. But are you? THOUGHT SO. I love her, so stop hating,' he wrote.

'I'm training her to fight and I’m willing to put her against whoever on @misfitsboxing and if you feel you can take her tag yourself In it. I'll set up a fight and you'll walk away with a bag. No less than $500,000 and percentage of PPV if it makes sense'.

He later posted in his Stories: 'On a semi serious note I have a new girlfriend. Not super serious at this time but she my boo. Ima teach her how to fight! She's the next one up @misfitsboxing.'

The couple's fledgling romance endured plenty of scrutiny after he announced his new relationship following his recent divorce Andrea Celina.
