Brad Pitt steps out looking skinny prompting fears he might be suffering an illness

Since his split from Angelina Jolie, Brad Pitt has become reclusive, coming out only once in a while and each time he surfaces, he seems to be looking slimmer than before, prompting fears that he might be ill.

Radar reported some months ago that Brad was spotted visiting an infectious disease specialist. Now, with his recent appearance, people are beginning to pay more attention to that report.

A source told Radar that Brad is ill but will have to face his illness alone, despite being there for Angelina when she had to go through a double mastectomy and hysterectomy. Sources close to Pitt have insisted that he is doing better than ever, even though the actor looked gaunt as he was seen headed to Los Feliz art studio over the weekend.

If his friends are indeed right that there is nothing wrong with him, then the only other explanation for his weight loss will be that his new look is in preparation for his next onscreen project Ad Astra, a sci-fi film which will see him play the role of an autistic engineer whose father left when he was young to try and find extra-terrestrial life on Neptune.
