James Van Der Beek's wife Kimberly is expecting their third child.

The 36-year-old actor and his spouse, who married in 2010, already have kids Olivia, two and Joshua, 17 months, and Kimberly took to her blog, oldschoolnewrules.com, to announce their happy news.

She wrote: ''James and I are happy to report that we are expecting our third child this winter!

''Nesting mode is starting to kick in. I've been getting rid of clutter, reconfiguring rooms, reorganizing EVERYTHING etc... my mind doesn't stop. I'm looking into meditation for that.

''All of the craziness, exhaustion and moodiness aside, James and I are beyond elated and feeling so incredibly blessed (sic).''

Kimberly also revealed their kids are happy about having a new sibling and she paid tribute to James for being a great husband and father.

She added: ''Olivia and Joshua are in on the news and seem to be excited about a baby coming into the family. And James, thank you for being the loving, caring and understanding husband and father that you are.''
