Did Justin Bieber just extend a virtual olive branch to Taylor Swift? That's what it looks like to us!

The Biebs may have just taken efforts to squash his epic feud with Tay (they've been at odds ever single the "Sorry" singer started making up and breaking up with her bestie Selena Gomez) by posing an Instagram video of himself singing Swift's breakout 2006 hit "Teardrops On My Guitar." And don't think the "Bad Blood" singer didn't notice -- she reacted by liking the video.

In the world of the Internet that's basically like kissing and making up!

In the brief vid, the 22-year-old sings as he sits in the passenger seat of a car and sings along to T-Sizzle's hit.

Back in August 2013, Us Weekly reported that Bieber's tumultuous relationship with Gomez drove a wedge between her friendship with Swift. It's been no secret that the "Shake It Off" singer disapproves of Bieber and has encouraged her BFF to cut all ties with the Canadian lothario.

But perhaps all that dislike is water under the bridge now?
