The Canadian singer and mum-of-two— who shares four-year-old son Wolf and three-year-old daughter Saskia with her ex, Reece— went public with their romance in late June and recently spent time together in Toronto, Los Angeles and the Gold Coast.
Last month, the mega influencer came under fire after refusing to take photos with her loyal fans while partying at the popular festival, Splendour In The Grass. After arriving by helicopter at an exclusive party hosted by Nana Judy at Angus Stone's Byron Bay property, apparently, the fitness fanatic also refused to be photographed with the brand's promotional team.
Her strange behaviour is a far cry from how she handled an appearance at Beginning Boutique's pre-festival gig late last week. She made headlines when a series of videos and photos surfaced of a braless Tammy riding a mechanical bull at a party.

The Instagram model— who hangs out with Keeping Up With The Kardashian star Khloe Kardashian and Kylie Jenner— ensured all eyes were on her ample assets wearing nothing but a tiny g-string under a see-through white netted mesh dress which was riddled with holes
Joined by a bunch of other "Instagram influencers", the 25-year-old— who was sporting a blue wig which she referred to as a "mermaid vibe"— didn't seem too fazed by her raunchy ensemble, happily busting out a few moves with her pals before jumping on a mechanical bull.
Tammy debuted her festival outfit to her. 9.7 million Instagram followers, with many users raving about her new hairdo' and daring look.
"I am loving this blue hair," one user commented. "Look at you, you gorgeous mermaid!!!" another added.
