Jessica Simpson insists she's 'stable and strong' amid fan concern

Last week, the singer/entrepreneur posted an advertisement for Pottery Barn to Instagram in which she showcased her three-year-old daughter Birdie's newly-decorated bedroom. However, a number of followers took to the comments section to note that Jessica sounded and appeared different in the clip. While not directly referencing the feedback, Jessica returned to the platform on Sunday to share a video of her singing her track Party of One in her studio.
