Since breaking up with Alex Turner last summer, there have been rumors that Alexa has been/dated Theo Hutchcraft, and now there are rumors that she is dating Albert Hammond Jr from the Strokes, but as we do not know Alexa personally we cannot confirm!!! 

I’m sorry, i’m a bit confused by your question. 

If you’re asking how to edit photos of Alexa on an iPhone, I have no idea, im sure it comes with a photo editor or you can get a app.

or If you’re asking how people edit those photos of Alexa from an iPhone, thats from her Instagram. 

We aren’t entirely sure but she seems to just be naturally skinny, there always has been some controversy about this, hence the recent issue she had with rude comments about her weight on her instagram. As we do not know Alexa personally, we do not vouch for her personal choices etc
