And Stephanie Hernandez and Denis Mikhlin are due to marry in a romantic New Year's Eve ceremony.

According to reports, the supermodel, 31, and her action star beau, 51, are gearing up for a lavish wedding reception with a massive bash held at their home in the Hollywood Hills.

The couple, who first met in 2010, became engaged in January 2016, with Stephanie giving birth to son John Gilmore Jr. in June 2017.

MailOnline has contacted representatives for the couple to inquire about their remarks.

According to People close to the couple, they had intended to marry in 2017, but decided against it until M&S model Stephanie gave birth to Jack.

Motherhood did not slow down when she landed in third place on Forbes' annual list of the world's top-paid supermodels in November, earning more than $13.5 million in less than 12 months.

Stephanie told Harpers Bazaar, 'We've been so concentrated on our jobs for so long, and Jack came along.'

We should certainly talk about it.' We're looking forward to that moment. We're also not a top priority for us; we're so happy. 'I think it will be amusing to do it after the baby's growth and that he will be involved in the wedding's.'

Stephanie led readers through the answers to her astonishing post-pregnancy figure in a conversation with Harper's Bazaar Australia.

The blonde beauty took her time" to reclaim control, according to Paul Matthews, who shared her experience.

'I believe I've felt the heat, but perhaps more from myself than anyone else.' I'm not one for extreme diets, so it's been a long time, and it's just now that I'm getting more comfortable,' she wrote.

Stephanie also admitted to working out four to five times a week, and that dance-cardio classes are a regularity.

"I just find that it's really good for me because I love it...I love that I don't have to go to a gym and have a personal trainer talking to me while running on a treadmill."

Kristin Austin, her Australian trainer, loves dancing with her mother-of-one at her namesake studio in Los Angeles, and she uses no weights or body bands during the performance.
