LLC + Branding for new biz

Hi Brooke and Coaches:

I have an LLC that my husband and I both use for our freelance media work. He does software. I do journalism. I’m going to launch my photography business full time starting in January 2019. This will be for private clients. Colleagues in the photo business tell me that I should have a separate LLC for the photo business that shares the name with my website and other branding, so I can better keep track of my photo business separately from my other freelance media projects and from my husband’s work. In your opinion, is creating a whole new LLC necessary or could I simply route my clients through my existing LLC, which doesn’t have the same name as my website and branding? Thanks!
