Singer Ariana Grande and Nathan Sykes of the boy band The Wanted have reportedly broken up. Us Weekly said that Grande and Sykes, both 20, have been able to see each other only rarely because of conflicting schedules. The two had confirmed in late September that they were a couple "So, I guess it's obvious now," Sykes tweeted at the time. "Thanks to everyone who is being so lovely. I'm so happy," he said, adding hashtags reading "but we're terrified" and "please don't kill me or Ariana." Almost immediately afterward Grande tweeted, "We hesitated saying anything as people can be a bit insensitive but thank you. We value all of your happiness, thank you for valuing ours." They had begun dating a month earlier, said Us, after having released their duet "Almost Is Never Enough" for the film "The Mortal Instruments: City of Bones." Grande also stars in the Nickelodeon sitcom "Sam & Cat."
