While visiting Las Vegas school Whitney Elementary as part of The Ellen DeGeneres Show, the 'Baby' singer took time out for a Q&A session with students after performing a private concert.
Asked how he and Gomez spend their time together, Bieber answered: "What do me and Selena do on the weekends? We go to the movies. And we kiss... No, we don't do that."
The 17-year-old also discussed the difficulties of his hectic career, revealing that he often misses his family and friends.
"Do I miss home? Yes, very much. 'Cause I'm always travelling and I'm always away from a lot of my family and friends. So, it can be hard. But, once I get to go home and see my family, it's always a pleasure," he confessed.
Bieber also donated $100,000 in cash and $100,000 worth of toys to the school, which has struggled with lack of funding.
Gomez recently confessed that she understands why Bieber fans hate her but is sometimes frustrated that they don't share a fanbase.
Earlier this month, it was revealed that Bieber will guest host a revival of MTV's Punk'd.
