Fans also rushed to speculate on rumors that this was Gray's way of letting fans know he's moving out of the famous Sway House. Many followers noticed that Gray took "Sway House" out of his Instagram bio.
However, fellow Sway House member, Bryce Hall, 21, reassured fans that they have no plans on separating. He tweeted, "none of the boys left sway wym."
"#sway4lyfe till the end," Gray noted in a separate tweet.
Just last week the lovebirds celebrated Thanksgiving together and shared an adorable photo cuddled up watching the ocean waves crash in Malibu, California. Zilber commented on Gray's post, "happiest<3."
Neither Gray or Zilber have publicly commented on the status of their romance amid all the speculation.
