But she's enjoying the 'fun' of it...
Talking in the September issue of Teen Vogue about her superstar boyfriend, she said: “It’s really fun. I’m lucky.
“I’m 20. I don’t take anything in my personal life too seriously. I have great friends and a solid group of people I love. I feel like everything else will come organically.
“Marriage and all that other stuff I think will happen once I feel accomplished in every other aspect of my life.”
Selena and Justin may have been together almost two years, but it seems Selena's more of an independent girl focused on her own career above anything else.
So don't expect to see them walking up the aisle any time soon!
