The Wilson family tree is officially expanding. After weeks of speculation, Owen Wilson's rep confirmed to People in October that he and his former personal trainer, Caroline Lindqvist, are indeed expecting a baby, and now a source tells the magazine that the bundle of joy will be a boy.

If so, it'll be the second son for the 44-year-old Oscar nominee — he has a 2-year-old, Robert Ford, with ex-girlfriend Jade Duell.

Caroline, 41, is still technically married, but a source tells the magazine that she was separated from her husband before she became involved with Owen. And though they're not living together — or together at all, even — the mag reports that they are on good terms and even teaming up to plan a December baby shower.

Other than this new addition to his brood, Owen has a ton of projects in production and development, including The Grand Budapest Hotel, his latest film with director and  frequent collaborator Wes Anderson. Then, of course, is the long-awaited Zoolander sequel, which will hopefully come down the cinema catwalk soon. But you can currently see Owen — or hear his voice, rather — in the animated comedy Free Birds.

Congrats in advance, Owen and Caroline! And hey, way to "work out" a working relationship.
