Justin`s Mother Worries About His Toilet Habits

She said: `I don`t know what Justin is going to do if he has to go to the bathroom. Those porta-potties are not cool!`

The ‘SexyBack’ singer is showcasing his William Rast clothing line at New York Fashion Week and before his show on Monday (16.02.09), his mom Lynn confessed she was more concerned about the inadequate bathroom facilities than the show.

She said: "I don't know what Justin is going to do if he has to go to the bathroom. Those porta-potties are not cool!"

Meanwhile, Justin brought chaos to a video shoot when he lost his dogs. The 28-year-old star – who is dating actress Jessica Biel - brought his three pooches along as he filmed the promotional clip for rapper T.I.’s song ‘Dead and Gone’. However, the singer soon regretted his decision when the dogs escaped from his dressing room.

A source said: “The dogs ran off and the crew had to catch them.“T.I. joked that Justin should have brought a fine woman along instead.”
