Ansel Elgort insists fame hasn't changed him.

The 'Fault in Our Stars' actor says he isn't interested in taking advantage of the perks of being a celebrity and just wants to focus on working with great directors.

The 20-year-old star said: ''What's changed is: 'Oh, you can go to this restaurant,' or 'You can go to this nightclub,' but I'm not really interested in that. I don't really care that some trashy girl, like, now all of the sudden wants to f**k me. That's not really that interesting to me.

''What's interesting to me is the fact that creatively I can do anything now and people will pay attention, and if I suck, hopefully they will stop paying attention very quickly, but if I'm good, then I have my foot in the door, and people have paid attention, and I did a good job, and people are like, 'Oh, wow!' That's sweet!''

The 'Divergent' star, who regularly communicates with his fans via Twitter and Facebook, thinks celebrities who use social media to air their ''dirty laundry'' are ''so sad.''

He told GQ magazine: ''I think celebrities that just tweet diarrhea from their mouths, that just tweet it in all caps, getting mad at things--those people are so, so sad, and they think that they deserve the voice.''
