If your are using the ShapeRenderer don't forget using setProjectionMatrix() and setTransformMatrix() methods...

A sample of draw circle inside an Actor on draw method :

@Override public void draw(Batch batch, float parentAlpha) {

    batch.end();

    if (shapeRenderer == null) {
        shapeRenderer = new ShapeRenderer();
    }

    Gdx.gl.glEnable(GL20.GL_BLEND);
    shapeRenderer.setProjectionMatrix(batch.getProjectionMatrix());
    shapeRenderer.setTransformMatrix(batch.getTransformMatrix());
    shapeRenderer.setColor(mColor.r, mColor.g, mColor.b, mColor.a * parentAlpha);

    shapeRenderer.begin(ShapeRenderer.ShapeType.Filled);
    shapeRenderer.circle(getX() + getWidth()/2 , getY() + getHeight()/2 , Math.min(getWidth(),getHeight())/2 );
    shapeRenderer.end();
    Gdx.gl.glDisable(GL20.GL_BLEND);

    batch.begin();
}
