On August 31, Tiffany returned to Instagram for the first time since her controversy and pressed "like" on one of GRAY's posts, but soon "unliked" it. Her actions have become the center of much suspicion among netizens. Comments stated, "Didn't believe it back then but after seeing this I think it's true. Tiffany and GRAY are together", "Why undo her like? She's dumb for making it more suspicious", "I thought she didn't go to Hawaii so she could reflect on her mistakes, but here she is liking her boyfriend's post", "Yep they are together", and more.
