Amber Valletta has completed a stint at The Meadows rehabilitation facility in Wickenburg, Ariz., a rep for the actress has confirmed exclusively to PEOPLE.
In a statement released through her publicist, Ame Van Iden, Valletta, 32, tells PEOPLE, "As was correctly reported earlier this week, my stay at The Meadows had nothing to do with substance abuse or addiction; I am pleased to say I have seven years' sobriety. But I continue every day to heal and grow as a person."
On Thursday, the New York Daily News reported that Valletta had sought treatment for stress and non-substance-related issues.
Valletta, an Oklahoma native, began modeling at 15 and has posed for Elizabeth Arden, Louis Vuitton and Versace, among others. From 1995 to 1996 she co-hosted MTV's House of Style with fellow supermodel Shalom Harlow.
Her first major film role was in 2000's What Lies Beneath, and she has since appeared in movies including 2005's Hitch and Transporter 2. Next year, she'll be seen in the thriller Dead Silence and the comedy My Sexiest Year.
She is married to pro volleyball player Christian "Chip" McCaw, 33; their son, Auden, is 5.
