Photos have surfaced online of the adorable duo getting cozy on the Los Angeles set of The Wanted's new music video earlier this week for their new single, "Show Me Love."
Grande and Sykes, both 20, couldn't get enough of each other as they were snapped hugging and locking lips during breaks between filming.
During one particular sequence he and his bandmates shot, the boy-bander, wearing a sharp black suit, ended up getting drenched in a hard rain.
And when he went to towel himself off, his singer-actress girlfriend was there to greet him with open arms and help dry him out, though not before sneaking a kiss...or two...or three!
After shooting was over, Sykes hopped a flight to Malaysia with The Wanted, leaving Grande behind.
The pair first found love after Nathan joined forces with Ariana for a duet, "Almost Is Never Enough," for the soundtrack of the adventure fantasy film The Mortal Instruments: City of Bones. Sykes also appeared in the music video as well playing piano.
After striking up a relationship, on Tuesday the baby-faced crooner let the cat out of the bag when he tweeted, "So I guess it's obvious now," and added, "thanks to everyone who is being so lovely. I'm so happy #butweareterrified #pleasedontkill me #orariana."
For her part, Grande was equally forthcoming: "We hesitated saying anything as people can be a bit insensitive but thank u. We value all of your happiness, thank you for valuing ours."
