Double headed anemone?

[Wanegrow]

Has anyone ever seen an anemone with 2 heads like this? At first i thought that 2 anemones had just found each other as soul mates, but after at least 3 months of this and it has moved around the tank several times On its own and I have never seen it separate partially or anything, i am starting to think it might be some sort of a freak of nature. Does anybody have any idea of what this is? I was told they are “Bornemans anemone” . I would appreciate any info, thanks in advance!
