Over the weekend, Selena posted a picture of her wearing the ring on Twitter - which features the initial J - as she holds someones hand, thought to be Justin's.
Accompanied with the snap of the diamond sparkler, Gomez wrote: "I'm finally home :)" - marking the end of her world tour which started last July.
Earlier this week, Gomez confirmed that she has split with her band The Scene, stating they were "going their separate ways for a while", as she concentrates on her movie career.
In a statement on her official Facebook page, Selena explained: "I can't express enough how grateful I am for this group. They have been with me since day one and I can't believe it's actually over.
"I love you The Scene, marsh mellow girls, Ashley & Ashlee, Jivanta, Marco, Brian & Brian, Mark, Jason, Javier, Timmy! Could NOT have done any of this without you. Currently bawling my eyes out. I'll miss you guys."
She later clarified: "My band and I are going our separate ways for a while. This year is all about films and acting and I want my band to play music wherever with whoever. We will be back but, it will be a good while. I love them and I love you guys :)"
