Exes Ariana Grande And Nathan Sykes Reunited For A Colab ; Boyfriend Rick Alvarez Worried?

Two years after their break up, Ariana Grande and Nathan Sykes are back in each others arms in a new romantic duet of Syke's hit single "Over And Over Again." After the Justin Beiber issue, should Rick Alvares, Grande's boyfriend, be alarmed about the reunion?

Rumors haven't stopped pointing out that the exes were reunited, as the two were so sweet in singing the song which is filled with romantic lyrics such as, 'I'll keep you safe and hold you forever'.

Ariana Grande's tweet also fuel up the issue saying that she was so delighted working with her ex-boyfriend.

The popstar Tweeted," #OverAndOverAgain by @NathanSykes ft me thanks for having me on this & congrats on the new incredible new music!"

On the other hand, Ariana Grande and her boyfriend Rick Alvarez are not seen in public recently. The couple has been rumored that they split up and Grande and Sykes are giving one another a second chance.

As recalled, The Wanted member revealed in his interview with E! News that he grasp inspiration from his past relationships in making his music.

"I poured my heart out a tiny bit in a couple of the songs, but yeah, that's a relationship that happened in my life and as a writer who draws from personal relationships and experiences, I think it's just natural that there's a song that fits that time in my life," Sykes said.

"Over and Over Again" is not the first time both singers collaborated in a song. Back in 2013, the boy band member did a song with Ariana Grande for her album "Yours Truly." That was the same year that the two dated.

Although the couple got separated, Ariana Grande and Nathan Sykes remain to be good friends, leading fans to hope that they would still be together as lovers.
