Jenna Dewan takes the plunge in saucy party dress while getting flirty with fiancé Steve Kazee

Jenna Dewan showcased her sensational figure in a plunging minidress, nine months after welcoming her son Callum Michael Rebel with fiancé Steve Kazee in March. 

As the lovebirds prepared to ring in the new year together on Thursday evening, the  Flirty Dancing host slipped into a pair of sky-high stilettos to watch the famous ball drop at midnight on TV. 

‘Had to remind each other what we looked like outside of sweats,’ the 40-year-old Step Up actress joked on Instagram as she celebrated New Year’s Eve at home.

In addition to putting on a very busty display, the mother-of-two rocked a glamorous makeup look, appearing happier than ever as she enjoyed quality time with her man. 

While the 45-year-old Tony winner sported a more casual ensemble than his bride-to-be’s provocative attire, they had fun making silly faces at the camera and he showed off his gold earring in footage on her Instagram Story.

The duo tuned in to watch Anderson Cooper and Andy Cohen co-host CNN’s New Year’s Eve Live from New York as they ate pizza and toasted with Dom Pérignon.

Her post comes less than 24 hours after she reflected on the ‘life’ and ‘beauty’ she experienced in 2020, as well as devastating loss due to the COVID-19 pandemic.

‘Oh, 2020,’ Jenna began her Instagram caption. ‘Looking back on pictures from this year…It has been challenging, humbling, heartbreaking, shocking and life changing to say the least.

‘I lost a family member to Covid, i have loved ones who lost loved ones and lost jobs. I’ve seen sides of people and this world that i wish i hadn’t seen,’ she continued.

Rather than losing faith in her fellow humans, Jenna zeroed in on the life-affirming aspects of the past year. 

‘There was also life, beauty and some of the most incredible experiences of my life..and so i choose to end this year feeling matured, humbled and grateful,’ she wrote.

‘Taking all the lessons of this year into the next chapter. be safe everyone, hang in there and sending love and peace to you all ❤️.’

Jenna opened the slideshow with a gorgeous image of herself from when she was pregnant earlier this year with her son.

In another image, she posed by some white blocks in a fierce scarlet dress with a high slit to showcase her toned legs. 

A cute photo with Steve showed them sharing a sweet kiss as they posed in front of their Christmas tree in one snap, while another showed the two from behind as they embraced her daughter Everly, seven, whom she shares with her ex-husband Channing Tatum.

Jenna met the Logan Lucky star on the set of their 2006 dance drama Step Up, and they shortly after production wrapped.

The two married in July 2009, before announcing their separation in 2018.

Later that year, she began dating Steve, and in September 2019 they announced that they were expecting their first child together.
