Emmy winner Mariska Hargitay was hospitalized Tuesday night, her rep confirms to PEOPLE.

"Mariska Hargitay went to the hospital this morning after experiencing some discomfort relating to her earlier lung condition," says the rep for the Law & Order: SVU star. "She is undergoing routine tests and expects to be feeling better soon. Production will not be affected."

Hargitay was hospitalized and underwent surgery for a partially collapsed lung in early January, but returned to work later that month.

Hargitay has not revealed the cause of her condition.

News of her hospitalization was first reported by TMZ.com.
