Jenna Fischer is expanding her brood!

The Office star's rep confirmed that she and her husband, Lee Kirk, are expecting their second child this summer.

Fischer gave birth to their first son, Weston, back in September 2011. "I had really underestimated what I was capable of because, before I had him, I thought I needed things that I didn’t really need... I want nine hours of sleep, but it turns out I don’t need it!" the 39-year-old joked last year.

Fischer and Kirk - who is a writer and director - wed back in July 2010.

“It looks like I need to get some new goals because I’m living my dream right now... [My husband] is amazing. He’s such a good father. I’m very lucky. I came to Los Angeles and wanted more than anything to be on a comedy TV show like Cheers. My other goal was to marry a great man and have a family," Fischer said back in 2012.
