James Van Der Beek is set to become a father for a second time after announcing his wife is pregnant again.

The Dawson's Creek star and his partner Kimberly became first time parents last September when they welcomed baby Olivia.

The couple has now declared they have a second baby on the way, just weeks after celebrating their daughter's first birthday last month.

In a post on Twitter.com, the actor writes, "Just when we thought we couldn't feel any more blessed, it seems the universe has plans to give our daughter a sibling... humbled."
