Why can't I create this Route53 CNAME Alias?

Question

I'm using fake-domain in place of what we really have.

This is what I have in R53 right now.

www.fake-domain.com     CNAME     xxxxxxx.cloudfront.net
fake-domain.com         MX        {typical MX records}
fake-domain.com         NS        {aws name servers }

When I try to add a CNAME ALIAS for fake-domain.com to www.fake-domain.com I get the following error:

InvalidChangeBatch 400: RRSet of type CNAME with DNS name fake-domain.com. is not permitted as it conflicts with other records with the same DNS name in zone fake-domain.com.

What record is it conflicting with? I don't have an A and the only root levels are MX and NS.

In Route53 Alias is only allowed when you have to point to AWS resources e.g. you may create cname alias to point to ELB DNS.
