Link a different gravatar account to WordPress

Hello all,

I recently started a blog https://planomania.com. I used a gmail address to set up this account. However, I had a wordpress.com account a long time ago set up with a hotmail address. For some reason I cannot for the life of me get my gmail gravatar account(which is completed and looks nice) to connect with my blog. It uses my gravatar account from my other account. I deleted the blog and hid the gravatar profile from the hotmail wordpress account but still nothing. It’s using the hotmail gravatar account. How did WordPress even know about that other account? I hadn’t used it for years?
Please help!
