Nothing equals the start of the holiday season like the lighting of a giant Christmas tree, and this expectant mother and star of the screen and stage was on hand to make sure if went off without a hitch. 

Jenna Dewan was a beaming and beautiful mother-to-be at The Americana At Brand 2019 Christmas Tree Lighting & Show on Thursday evening in Glendale, California, wearing a beautiful navy blue maternity dress that showcased not only her growing baby bump, but her gorgeous figure as well.

Dewan, 38, wore a floor-length gown that was incredibly low-cut, accented with sexy black lingerie motifs at the chest, waist and cuffs.

Jenna's gown also featured a higher-than-high slit up the side, letting her leg peek through, and from the empire waist hung a tasseled belt.

The Step Up star, who is expecting her second child with her Tony-winning beau Steve Kazee, perched on black strappy heels, and let her gorgeous dark hair hang loose in front of the lavish holiday display.

Along with Kazee, 44, Dewan sat for the ceremony next to their friend Leighton Meester of Gossip Girl fame, along with Caruso founder and CEO Rick Caruso and the mayor of Glendale, Ara Najarian.

Leighton, 33, was dressed in a decidedly tamer outfit for the holiday event, in a beige maxi wrap dress with polka dots.

Make a statement in a Paule Ka dress like Jenna

Jenna Dewan got us in the mood for Christmas after we spotted the actress at The Americana at Brand 2019 Christmas Tree Lighting & Show this week.

For the event, she opted for a luxurious look with the help of her trusted stylists Brad Goreski and Daniela Viviana Romero, who dressed Jenna in this gorgeous satin maxi dress by Paule Ka with Stella Luna sandals.

The ‘Riso’ dress is designed with billowing sleeves, a plunging V-neck trimmed with black lace and a draping slit-front skirt. The dress perfectly shows off her blossoming baby bump thanks to the loop embellishment on the waist that cinches in the figure.

The green version is available to buy at Farfetch via the link (right), but if you want to be bold in blue for your own event then peruse our picks below. Replicate Jenna in a dress no matter your budget with alternatives by Asos, The Line by K or She by Sophie.

As reported by Just Jared, the event was hosted by Tall Girl‘s Ava Michelle.

The festivities included a show that featured performances from Joseph Tran of The Magic Castle, Ella Rossi and the West Angeles Choir.

Jenna took to her Instagram stories to showcase the giant tree in all its glory.

Dewan, who has enjoyed a career as a dancer and actress, is also mother to six-year-old daughter Everly, who she shares with her ex-husband Channing Tatum.

Tatum and Dewan finalized their divorce last year, shortly before she was linked to Kazee, who has found success on the Broadway stage in New York.

Channing, for his part, has since been linked to British pop sensation Jessie J.
