Actors Jonathan Rhys Meyers and Mara Lane have welcomed a baby boy.

Welcome to the 2017 edition of: celebrities giving their kids unusual names.

Last year saw such baby name bangers as Dream Kardashian, York Banks (Tyra Banks), Boomer Phelps (Michael Phelps) and Journey River Green (Megan Fox).

Mission Impossible III actor Jonathan Rhys Meyers and his fiancee, actress and producer Mara Lane, have now kick-started the 2017 list with the birth of son Wolf Rhys Meyers on December 15.

The December birth might technically disqualify Meyers, 39, and Lane from the 2017 listing but the confirmation to E! News just came through, so let's make it an exception.

It was reported Meyers and Lane began dating in 2014 before announcing their engagement in December of the same year.

News of the pregnancy was announced only three weeks ago in an Instagram post by the couple. Lane spilled the baby beans with a picture that compared her bump to a similarly rounded Santa Claus.

The sudden post was soon followed by two more that pictured the mum-to-be showing off her maternity wear bargains.

"My official pregnancy dress. I have worn this 1-2x a week every week for past five months. It was three euros in a charity shop in Ireland," she wrote.

Wolf Rhys Meyers, now almost three week old, is yet to have his photo shared publicly.

If the pregnancy announcement is any timeline to go by we can expect a first look anywhere between now and... eight months?

Wolf joins a whole pack of other animal-inspired celebrity babies such as Zooey Deschanel's daughter Elsie Otter, Alicia Silverstone's son Bear Blu, Nicole Richie and Joel Madden's son Sparrow, Kate Winslet's son Bear Blaze, and Erykah Badu's son Puma, to name a few.

We'll be hunting down pictures of Wolf as soon as they're released. Till then, we'll tide you over with a whole gallery dedicated to our favourite celebrity dads.
