Jane Douglas (Outside Xbox)

With her degree in physics, this half-Chinese British beauty is as smart as she is hot. As the only female host of gaming news channel Outside Xbox, she does the bulk of the legwork (literally, at times) in the eye candy department, but has also made appearances on various panels about the games industry in general, and has even presented awards at the BAFTAs. Beyond YouTube, she pulls in viewers with her Instagram, where she regularly posts spandex-clad gym selfies, glamour shots, and even the occasional bikini pic.
