I believe she has androgen-insensitive syndrome. That is a condition where a genetically male child (XY chromosones) will be conceived, but its body is insensitive to testosterone and so will develop as a female. Androgen-insensitive women are externally female, but they have no internal female reproductive organs. They do have undeveloped testicles, but they are inside the abdomenon (about where the ovaries would go) not “hanging out” like a man’s. Many times they are surgically removed to avoid the risk of cancer.
Since they are not affected by the testosterone in their bodies, androgen-insensitive women tend to look more feminine than other women. They generally have large breasts and little or no body hair. They don’t have problems with pimples or thinning hair. Given this it should be unsurprising that many beautiful actresses and models are androgen-insensitive, although few are “out” about it.
