It seems pretty common for people to assume those women who have nice breasts (particularly fuller ones) have had breast implant surgery. Keeley Hazell appears not to have had implants. Her breasts feature more of the signs of natural large breasts than implanted breasts.
Breast implants tend to look more round without help. You will notice Keeley (like many women with larger natural breasts) tends to wear bras and bikinis that support her and pull her breast tissue up and together to form cleavage. The softness of natural breasts is not easily mimicked with implants alone. Breast implants also tend to produce upper pole breast fullness without help.
So my vote on Keeley is “No implants” at least for now.
