Bristol of course is a grown woman, chronologically at least, so she can do what she wants on social media. But encouraging Tripp to participate in her desperate attempts to emulate the Kardashians is just pathetic.
By the way Sunny Johnston sometimes shares pictures of Tripp as well, however hers are more along these lines.
P.S. And before you ask me what is up with the Johnston-Palin hyphenated name, I have no idea.
