A couple of weeks after confirming they're a couple, the singer and her boybander beau held hands as they headed out of SushiSamba in London Wednesday, with 20-year-old Ariana stopping to give Nathan a kiss on the cheek before they made their way out.
Clad in a mini-dress, a plaid coat and knit cap, the "Way" crooner couldn't help but flash a smile after their romantic date night.
This the latest sighting of the couple, who also stepped out Tuesday for Bruno Mars' concert at the O2 Arena.
"Had the most amazing time at @BrunoMars show tonight. His vocal ability is beyond incredible. I'm obsessed," Nathan tweeted that night.
The Wanted singer recently said Ariana has already met his parents, telling Digital Spy, "I took her back to Gloucester yesterday to meet all my family. I was so scared, you don't even realize. But my family think she's amazing and they're like 'Nathan, how?' and I'm like 'I don't know.'"
He added, "I don't think anyone can ever punch above their weight, but I feel very lucky, put it that way."
In addition to saying that his bandmates "love her," Nathan couldn't help but keep gushing over his ladylove, saying, "She's amazing, I'm so happy... she's a really special girl, I think the world of her and I hope we'll be together for a very long time."
