Did he initiate contact? Did he say much more than happy birthday? Is there some evidence showing that he was grooming her in the intervening years? "Waited until she's legal" kinda obfuscates that there was a 4 year gap and she was 22. Obviously playing the long game there...The fact that he started talking to her when she was a minor (that she porvide proof of), and after she become older he started to have sexual conversations and used his celebrity status to manipulate her to just have sex and dump her immediately after it, doesn't make it look less of a creep.
Just because he waited for her to be legal, doesn't make him look less of human garbage.
And apparently the source of this is an account that literally only posts and comments in the rantgrumps subreddit.
