Dazzling Jenna Dewan Tatum Shows Off Her Cleavage in a Plunging Champagne Gown at the American Music Awards

She works hard to maintain her envy-inducing dancer's body.

And Jenna Dewan Tatum proudly displayed her knockout figure during Sunday's American Music Awards at the Microsoft Theater in downtown Los Angeles.

The World Of Dance judge, 36, commanded attention in a shimmering champagne dress which plunged low to reveal the starlet's cleavage.

The gown also revealed a healthy amount of Jenna's toned legs with a ultra-high slit and semi-transparent skirt.

Turning around, the mother-of-one showed off her pert posterior as she worked her magic on the red carpet.

Jenna - the wife of Magic Mike hunk Channing Tatum - teamed the look with gold heels, diamond earrings and a collection of ornate rings.

The star styled her dark tresses into a choppy chic bob with a messy side-parting.

Jenna accentuated her striking green eyes with shimmering make-up.

It was no wonder she dressed to impress, with the Step Up star presenting an award on stage alongside Billy Eichner.

The mother-of-one offered followers a behind-the-scenes look at her pre-awards routine, sharing a photo of her in a robe besides her daughter Everly, four, with the caption 'AMAs pre-show.'

On her way to the event, Jenna posted from the car, writing: 'Here I come AMAs.'

Sunday's star-studded event featured some of the most famous musicians in the world.

Bruno Mars led the evening's nominations with eight, followed by Ed Sheeran, Drake, Kendrick Lamar, The Chainsmokers and The Weeknd, who each have five nominations.

But the most interesting category is Best Female Pop/Rock artist with Rihanna and Lady Gaga going head-to-head with newcomer Alessia Cara.

Artist Of The Year was dominated by men with not one woman listed.

The nominees are Bruno Mars, The Chainsmokers, Drake, Kendrick Lamar and Ed Sheeran.

The night will also feature many performances from the biggest artists in music including Selena Gomez, Demi Lovato, and Lady Gaga.

Pink will have her most daring performance yet as she has been seen practicing a routine while hanging off the side of a hotel building over the weekend.

Pop veterans Christina Aguilera and Kelly Clarkson will be hitting the stage.

Black-ish actress Tracee Ellis Ross is host of the event as her legendary musician mother Diana Ross is also a featured performer.
