January Jones celebrated her son’s birthday with a nude pregnancy photo

There’s no better way to celebrate a birthday than by sharing a throwback photo. Take January Jones, who shared a nude pregnancy photo in honor of her son’s 6th birthday. While it might be embarrassing to her son (because he’s a kid, and this is his mom) we can’t help but notice the ethereal beauty that radiates from this shot.

In the photo, the Mad Men star poses underwater, with her growing bump on full display.

Since Jones was a bit private during her pregnancy (especially since she kept making headlines for keeping her son’s father a secret) it’s rare to get such an intimate glimpse.

Xander Dane Jones was born back in 2011. While it’s a bit uncommon to catch a glimpse of him, Jones has been fine with sharing photos on Instagram for events like his birthday — like this one from last year.

Earlier this year, Jones revealed that she thinks her son is better off with having a single parent and noted that she had no regrets about how she handled the pregnancy back in the day.

"My younger sisters and my mom and my doula were in the room; my brother-in-law and my dad were next door. I only wanted women with me. Female energy," she said in an interview for the February issue of Red when asked about giving birth. "It was a 30-hour process but it was awesome. I'd love to do it again."

She also admitted to the magazine that Xander had plenty of wonderful male role models around.

"Xander has a lot of bro time with the neighbor dads and my dad, who is super young. It's good to have strong women around a man to teach him to respect women," she said.

We think that Xander is growing up to be a pretty incredible kid (all thanks to January), and hope his fifth year is full of love and joy.
