Whether you love it or hate it, Ariana Grande and Nathan Sykes are madly in love. "The Wanted" singer recently brought his girlfriend out on stage during the band's performance in LA and enchanted her with a song "Heart Vacancy".

Embarrassed Ariana tried to run away from the stage but Sykes' fellow band mates made sure that Grande graced the stage with her boyfriend.

Nathan sang while Ariana snuggled in his arms. According to Nickutopia.com, this whole thing was planned by manager Scooter Brown as he thought it will be good for the couple's relationship.

Ariana and Nathan Sykes have been dating each other for more than two months now and it appears they are inseparable.

However, "The Wanted" member Siva Kaneswaran thinks that their relationship is not as flawless as it seems. He told Yahoo OMG that,

"They are struggling because they're brand new in a relationship. I think that's actually a struggle right now, they know how hard it is in the beginning. It's going to be hard, they need to focus on each other...I know all the short-cuts now, but they'll have to learn all that. I've been with my girlfriend for six years now and we're really, really happy. We've sorted out priorities out. Every relationship's different; we just have to keep it consistent."

We don't agree with Siva here. He may be right in saying that Nathan and Ariana have to focus on each other but in no way they are "struggling". They are too much in love and their recent public outings are a testimony to it. Last week, they were attending musical concerts in London and this week they are having a great time in LA.

What do you think about Ariana Grande and Nathan Sykes' relationship? Will it last?
