Jessica Simpson - Jessica Simpson's Windy Meeting

Jessica Simpson accidentally farted during an important business meeting.

The American singer passed wind as she was speaking to executives about her denim clothing line, and was told off by her mother Tina who was mortified that her daughter had displayed such bad manners.

A source said: "While one of the executives was speaking in a room full of five people, Jessica let out a very loud fart.

"Her mother Tina Simpson was there, and it prompted her to turn around and yell, 'Jessica!' The tension was extreme. No one knew what to say."

The reality TV star previously revealed she wanted to release her own range of denim garments because "a girl's booty needs to look good".

The incident isn't the 29-year-old star's first brush with public flatulence. Jessica once farted during an episode of her TV series 'Newlyweds'.

She then went on to tell her then-husband Nick Lachey: "You love my stinky a*s."
