She seems sweet and fun. Sometimes a little frantic in her delivery but many might just call that enthusiastic - I watch her but wouldn't do so for relaxation! I liked her trying all different kinds of yoga video.
Sierra has her fair share of issues, and her blonde friend Skylar left social media/the channel when she had a baby
Made everyone unfollow her on Instagram (instead of just making a new private one) and hasn't been seen since.
