The 35-year-old, whose wares included her 10th anniversary collection's gray jeans, appeared with her mom, Tina Simpson, in a two-and-a-half-hour spot with Colleen Lopez. During a few short segments from the lengthy appearance, Jessica Simpson slurred her speech and wobbled unsteadily on camera.
While trying to promote her collection's "Kiss Me" Super Skinny Gray Jean, the mother of two rambled emphatically about her sister Ashlee Simpson and her husband, Evan Ross, as seen in unauthorized clips that surfaced on YouTube.
"Ashlee is like the best at wearing gray. My sister. Like, she's very rock 'n' roll, but there's something about a gray that's like sexy. Maybe it's her and her husband, they share jeans, I have no idea. I don't know. There's just something hot about them," she said, flailing around a bit by the demo rack.
Twitter users brought attention to her bizarre behavior by re-appropriating Simpson's hashtag #JessicaonHSN. There, several accused the blond star of being drunk on television.
The clip was markedly different from Simpson's numerous bubbly and professional TV spots last week while promoting her clothing line at New York Fashion Week.
Simpson's publicist declined to comment on the appearance and the singer did not make any public remarks after the show.
A source told E! News that Simpson "was not drinking" during the show.
In a statement, HSN said "it was fun" to have the designer and her mom make their debut on the network: "We were happy to host them and thrilled with the way customers responded to the collection."
Lopez didn't acknowledge the inadvertent attention her segment received, and instead took to Facebook to congratulate the star on a sell-out show by posting a selfie with Simpson.
"Thank you so much for watching tonight!" she wrote. "Congrats to Jessica Simpson and her Mom, Tina on a sell out show!!"
