Assuming you want an image circle with a white background, like this:
To do this in Lightroom:
1. Crop & Straighten Tool: Crop to square/rectangle, so circular image is in center of the square/rectangle.
2. Post-Crop Vignetting: Slide sliders to produce desired effect. These settings might get you close.
Lightroom can produce a white or black vignette like this. If you need a different color of background, a transparent background, or better control of the circular shape, then a pixel editor (such as Photoshop) would be the appropriate tool.
