duffsterpreggers.jpg Star Magazine is reporting that Hilary Duff and Mike Comrie are expecting their first child together, but Hilary's rep tells X17online that the actress is "not pregnant."

A source told the mag, “They weren’t actively trying to conceive but agreed that if it happened, it happened ... They’re ecstatic."

Duff and Comrie tied the knot in Santa Barbara last August, and while Duff has made it clear she's eager to start a family, apparently she plans on waiting a little bit longer!
