Nathan Sykes and Ariana Grande are slowly becoming the cutest couple in Hollywood. Could the "Nariana" duo be the replacement of the former power couple, "Jelena?" Well, these two don't have to try hard to look adorable for anyone else but themselves. Here is Nathan and Ariana's cutest couple moments caught on camera plus all the latest drama involving Ariana's ex-beau, Jai Brooks.

The Wanted singer, Nathan Sykes and his beautiful girlfriend, Ariana Grande are certainly the cutest and hottest young couple in the pop industry. Despite being surrounded by drama, the "Nariana" couple have become stronger than ever. As for Jai Brooks, Ariana's ex, claims of Grande cheating on him, Perez Hilton claims it was all made up for fame.

"I know the two well and this is a classic case of a nobody trying to use someone's fame as a way to leverage his own pursuit of stardom. Ariana never cheated on Jai," stated the source.

Not only did the claims shock "Jariana" fans but it certainly wounded Ariana Grande.

"How he handled it was a bit unexpected, but at the end of the day my family and my friends and my true fans know the kind of person that I am. Those kind of accusations are completely false and more than anything hurtful and shocking," stated Ariana in an interview with 4Music.

For now, Grande's heart is under mending by none other than British singer, Nathan Sykes. Reports claim Justin Bieber played cupid to the two stars.

"It was a really fun day - he was very sweet and cute," said Ariana Grande, adding, "We started talking and then it just went from there. No, actually we didn't really start talking until we met again at Justin Bieber's tour in August."

Grande and Sykes had met initially on the red carpet last March but nothing happened back then.

"I saw him in March on a red carpet, and we locked eyes with each other all night," revealed Grande.

"I thought, he was cute as [heck]. Nothing happened obviously and then, the duet came about," continued the singer.

Obviously, the "Nariana" couple are head over heels in love. It was just last week that Nathan had introduced Grande to the Sykes family back in the UK. Hopefully, things go smoothly between Ariana and Nathan. Check out the slideshow to see more photos of this adorable twosome.
