Earlier this week, tongues were wagging about a potential romance rekindle after fans shared snaps of the couple apparently dining together at Dave & Buster's in Los Angeles on Monday, August 25.

The following day, Bieber added fuel to the fire by posting a picture of his one-time girlfriend Gomez on Instagram, and then quickly deleting it.

However, judging by Bieber's latest Instagram share, the couple's relationship status is becoming less ambiguous. The cute duo cozied up for a selfie in Canada on Wednesday, Aug. 27, and the picture still hasn't been deleted from his account!

A source tells Us Weekly the "Boyfriend" singer jetted to his homeland on a private plane from Los Angeles on Wednesday morning. Fans shared video of his and Gomez's arrival at Waterloo airport in Ontario later in the day.
