Fans of Selena Gomez and Justin Bieber were thrilled to see the controversial couple back together. The Canadian pop star posted a photo of him hugging the songstress on his Instagram account a few days ago, but he deleted it right away.

After seeing that post, many people assumed that they are officially a couple again. I'm pretty sure Taylor Swift wasn't happy about it, but let's hope that this time Selena did the right decision of taking Justin back.

Their relationship was confirmed when Justin's close friend Khalil posted a video of the birthday party of Alfredo Flores. In the clip, you will see Selena Gomez and Justin Bieber looking cozy with each other. The video was captioned "Happy Birthday @AlfredoFlores!!!!"

Alfredo also teased his followers by posting a blurred photo of himself together with the couple. He captioned the photo "Blurred night with these 2! Happy Birthday Me!" One follower commented, "Yees they are back guys".

Another proof that Justin was really at his party was when he tagged the musician in his Instragram photo. He captioned the photo, "Thank you to everybody that came out last night to celebrate the Bday! Here's to another year of life! | cc: @quincy @kennyhamilton @justinbieber @coreyg650"

An insider revealed to E! News that Selena Gomez and Justin Bieber kept telling everyone that they have reunited. An eyewitness said, "They were holding hands and showed some other PDA, but no over-the-top making out or kissing."

The eyewitness added, "They were together the whole night and left together at the end of the party." That clearly proves that they are giving their love another chance. Another source told the website, "He [Justin] has been trying to patch things up with Selena...He does love her."

Love is easier said than done. I wonder how long will the Selena Gomez and Justin Bieber relationship last. Do you think this time it's for keeps?
