Mariska Hargitay has returned to the Law & Order: SVU
set, two weeks after news broke that the actress had suffered a partially collapsed lung.
"She's back at work," her rep confirms. A rep for the production company also confirmed that Hargitay was on SVU
's set as of Monday afternoon.
Hargitay's absence caused filming to cease last week, according to sources. Although she was nominated for both a Golden Globe and a SAG award for her role as Det. Olivia Benson, Hargitay was absent from both of those awards ceremonies this month.
Hargitay, 45, has not released any information about what may have caused her partial lung collapse.
