Sad to say, but IDK that it's the alcohol. I'm sure the alcohol doesn't help, but I think she's just a naturally out of touch, delusional person with absolutely zero self-awareness. She's been insufferable this season. She was ok her first 2 seasons, when she was humble, but even then, there were signs that she was way out of touch with reality and took herself too seriously and had no idea how to act, like when she told Kristen and Stassi to "wrap it up" at Katie's engagement party. Last season, I kept cringing at how seriously she took herself but she was still at least somewhat humble and grounded. This season, she's completely lost it. I think she needs a lot of attention at all times. I think she's very needy and ungrounded. I literally cringe every time she speaks.
Even on her IG, I'm just like wtf? She posted something about how she had facial fillers, which is whatever, who cares, but then she went on about how she wanted people to know "it's ok to get plastic surgery and it's also ok to be natural, whatever it is, do you, baby." Like thanks Lala, we so need your "ok" to do what we want with our bodies! She talks down to her followers like we're all teenagers or something, that should worship her, the star. I wish she's allow comments, but of course, her ego is way too fragile for that.
