You have posted this in the CrazyTalk forum so I'm assuming you are using CrazyTalk 8 rather than Crazytalk Animator 3. If that is the case then you can't add accessories to a 2D head in Crazytalk itself.
So if you wish to add a cigar to your character, it will need to be added to the source image before you create your head. This will involve finding a suitable photo of a cigar, and then using your image editing software to cut out the cigar and paste it into your source head image. However you won't be able to place the cigar in the mouth if you plan to have your character is talking, but if the cigar is to be held that shouldn't be a problem.
