Jaime Pressly wants to set the record straight about some photos and video circulating the Internet that seem to show the actress urinating on a public street in the middle of the day.
In a message posted on her Twitter page, the actress explains why she may have been photographed outside The Abbey, a bar in West Hollywood, crouched over a wet floor and holding the bottom of her dress.
"Yes ... that is me doing dare # 8 at my bridal shower," the newly engaged
Wednesday. "Things are not always what they seem."
Those who saw the My Name Is Earl
star, 32, outside the bar on Sunday thought otherwise, as shocked patrons can be heard gasping in a video posted earlier this week on PerezHilton.com.
"Notice my hand in the back," adds Pressly of the prank. "It's pouring a bottle of water!!! C'mon guys! Do you think I would really pee in the entry way to the Abbey in broad DAYLIGHT!!!"
"Way to spin a story!!!" she says in another message.
