OF AGE McAdams

The star of Wedding Crashers and The Notebook claims she was born in October 1978, making her 28. But imdb.com puts her birthday in 1976—and those who've looked into the matter believe the earlier date may be accurate.

In a November 2005 profile, Details listed McAdams's age as 29, prompting her then-publicist, Ame Van Iden, to complain vigorously. (McAdams later fired Van Iden, reportedly because the flack booked her to appear nude on Vanity Fair's cover without her consent.) A Details source says the magazine agreed to run a correction only after Van Iden assured them that IMDb had been notified of its error.

As of yesterday, however, the site was still listing her as 30. When Elle wrote McAdams up for its April cover, it got around the problem by saying, "IMDb states [she] is 30, but [she] is really, truly, ask her mother, 28."

What's the truth? "Her birthday is inaccurately reported," says her rep. "She is 28 years old." But a source involved with one of her recent films says it's "no secret among the producers" that she shaves a couple years off her age in interviews—only to add them back on when she's up for a part that calls for a more "mature" actress.
