"Jelena" is officially together and everyone knows all about it. Justin Bieber has finally won her lady love back after loads of persuasion and talking on a radio show about how he truly loves the Texan beauty from his heart forever. Let's look at top 5 reasons why Justin and Selena are back as a couple:

1. Demi Lovato: Do you know the person behind the reunion? You will be surprised to know that singer-actress Demi Lovato has reportedly convinced Selena Gomez to spend some time with her ex-boyfriend Justin Bieber. "This was spearheaded not only over her lupus situation but the more she has been talking to Demi Lovato who is on her own break really made Selena take a look at her life and realise what is important and that is to enjoy some normality while she is young," says a source to Contactmusic Web site.

2. Both Needed Company: It gets lonely at the top. Both Justin and Selena have fabulous careers and it is very difficult to find genuine friends when you are a star. Justin and Selena have been buddies since such a long time now and know each other inside out. It was always a good idea if they both reconcile than finding new friends.

3. Justin Still Loves Selena and Can't Get Over Her: The "Believe" singer confessed his love for Selena Gomez in one of the radio shows. He said he still has a soft corner for her and wanted her back. Selena probably felt awesome hearing all good words for her from her ex-lover and got back when she got in his city.

4. Selena's Lupus: Selena cancelled all her concerts saying she wants to spend some time with herself alone. But the real reason was that the 20-year-old is suffering from auto immune disease Lupus and too much dancing and exertion could hamper her health. Justin Bieber did not want to leave Selena alone when she needed him the most at this critical stage. So he got back with her to help her overcome the illness.

5. Holidays: Both Selena and Justin had ample time at their disposal because of the Christmas and New Year holidays. Everyone wants to get back to their loved ones during the holidays. Justin and Selena were spotted spending some good time together. Justin even Instagramed a picture of himself posing cosily with the "Slow Down The Music" singer proving to the world that he is no longer single. Selena and Justin were spotted earlier in the Oaks segwaying together. "There is zero time table to return to concerts or movies. She is enjoying her time away from work and spending it with her family and Justin," added the source.

The couple has yet to confirm to the media about their reunion but fans are happy to see the couple together again. The love birds also took a short break together in Northern California and were spending some relaxed time at a beach resort.
