Law & Order:SVU Mariska Hargitay suffers relapse!

"Mariska Hargitay has been sidelined with a pneumothorax," her rep confirmed.

In layman’s terms – that‘s a collapsed lung.

That’s the second time that’s occurred in less than a month, according to sources.

Pneumothorax  occurs as a result of the buildup of air in the space between the lung and the chest wall, according to Web MD, often occurring after a broken rib.

Her rep says Hargitay was not injured during filming of the action-packed NBC series and "will appear in all episodes for the rest of the season" despite being a no-show for the Golden Globes after being nommed as Best TV Drama Actress.
