From "Tool Time" to diaper duty: Home Improvement funnyman Tim Allen and wife Jane Hajduk are expecting their first child together this spring.

“Tim Allen and his wife Jane are ecstatic at the upcoming birth of their first child together," the actor's rep, Marleah Leslie, confirms to OK!. "The baby is due in Spring  2009.”

Tim, 55, and Jane, 42, were married in a small family ceremony in Grand Lake, Colo.  in October of 2006, after dating for five years. This is the couple's first child together; Tim is also father to 19-year-old Katherine "Kady" Allen, his daughter from his first marriage to high school sweetheart Laura Diebel.

The star of The Santa Clause films and his actress wife have appeared in a few movies together, including Zoom and the comedy The Shaggy Dog.

Tim's next film Crazy on the Outside is due out later this year, while his voice talents as Buzz Lightyear in Toy Story 3 will debut in 2010.
