Arzaylea's 21, she's a couple months younger than Ashton, and yeah he'd only date someone around 3-4 years younger, no younger than that for a while, especially not until the person in question is over 18. I'm 5 years younger than him so I get it but I know I wouldn't ever have a chance considering they have at least 10 million fans and we've never met. To be honest, as long as he's happy I don't care who he dates.
