Josh Brolin’s wife Kathryn happily shows off her baby bump during a workout at a gym… just days before her due date

Josh Brolin and his wife Kathryn are expecting the arrival of their second child together before the end of the year.

And even with the prospect of giving birth in a matter of days, Kathryn hasn’t eased up on her exercise regimen, as seen in an Instagram post over the weekend where the model is happily showing off her baby bump.  

‘Sorry for all the belly pics. I just like documenting the last part of this journey, #38 weeks,’ Kathyn revealed in one of the video clips of herself working up a sweat at a gym.

The 33-year-old rounded out her sporty ensemble with black sneakers and her long blonde tresses pulled back off her face with an orange headband.

Working it: Kathryn made the rounds at a gym this weekend, which included doing squats while showcasing her baby bump in a sporty ensemble

Kathryn could be seen doing squats using her own body weight where she wrote: ‘ I think I’m alright.’

After doing several sets on her legs at various leg angles, she moved on to some exercise machines, including a stationary bike and a lat/pull down device.

But still, no matter the exercise or the machine, Kathryn looked to be thrilled to be working out, from the big smile she routinely flashed during her time in the gym.   

The couple revealed earlier this summer that the family had relocated to Georgia from Southern California for a ‘new adventure.’

Kathryn announced her pregnancy news in July by sharing a photo of herself baring her growing midriff in a crop top and denim shorts as she gave her daughter Westlyn a sweet smooch. 

‘The Brolin’s are a growin’ !! Our little December babe is on the way….’ she wrote in the caption.

Josh, 52, left a cheeky comment on the post, writing, ‘Wow. That’s amazing! Congratula … wait … WHAT?!?!’

The couple, who celebrated their fourth wedding anniversary in September, welcomed their little girl, Westlyn, in November 2018.

Josh also shares son Trevor Brolin, 32, and daughter Eden Brolin, 26, with his first wife Alice Adair, who were married from 1988 until 1994.
