Although Amy had been involved in the business from day dot, the fitness model said their constant arguing eventually took a toll on their personal relationship— with the star admitting her sister didn't talk to her for several days after she was let go.
"Now that [Amy] hasn't been working for me for a little while, it has actually made us get along so much better. I don't regret it."
"The truth is, I do feel like I know what's best for you. It's really good for me too, though. I always felt that Saski was Tammy's baby," Amy said, before admitting she's since started her own business with their other sister, Emillee.
Last month, Tammy made headlines after hinting her boyfriend Jahkoy Palmer had popped the question. After sharing a couple of fully clothed mirror selfies in which her ring finger was noticeably hidden, fans were quick to assume the couple had taken their relationship to the next level, just months after sparking split rumours.
Her Canadian rapper boyfriend then added more fuel to the fire when left an engagement ring emoji in the comments section of her snap.
"Oh my god, you are perfect together," one fan wrote after noticing her beau's cheeky comment. "FINALLY! Congrats," another follower added.
After thousands of comments flooded in congratulating the couple on taking the next step in their relationship, Jahkoy (or Tammy) deleted the comment.
The Australian fitness influencer and her rapper boyfriend— who has collaborated with Jaden and Willow Smith in the past—went public with their romance in June, a little over a year after Tammy endured a very messy breakup with her ex-fiance, Reece Hawkins. The former couple, who were together for over five years, share four-year-old son Wolf and three-year-old daughter Saskia.
