Pregnant Kim Kardashian glows with pride as she cheers on stepfather Caitlyn Jenner at ESPY Awards in one-shouldered LBD

She received a standing ovation when she was recognised with the Arthur Ashe Courage Award on Wednesday night. 

And among the packed crowd was Kim Kardashian, who glowed with pride as she cheered on her stepfather Caitlyn Jenner.

The pregnant 34-year-old watched the Olympian, 65, address guests at the ESPY Awards in Los Angeles beside her beaming sisters Khloe Kardashian, 31, Kourtney Kardashian, 36, Kendall Jenner, 19, and Kylie Jenner, 17.

As per usual, Kim was immaculately dressed for the occasion.

The expectant mother-of-one polished up in a stunning black dress that was slashed at the shoulder and adorned with a gorgeous pearl detail in place of the sleeve.   

Her raven black locks were slicked back into a chic and no-fuss bun, and her complexion radiated with bronze blush and full lashes.

Put on your pearls girls in an embellished dress like Kim's

She might not have walked the red carpet at the ESPY Awards, but that didn't stop Kim Kardashian stealing the show from the crowd!

The pregnant reality star shunned her usual sheer styles and instead showed off her penchant for pearls in this black asymmetric gown. When teamed with swept-up hair, it's a very elegant look and we have to say we love it.

It's by Alexandre Vauthier, the designer label that Kendall also chose to wear on Caitlyn's big night. Featuring the pearl embellished detailing that was a running theme throughout the Fall 2014 Couture collection (check out the similar dress pictured, right), it's a subtle but sophisticated touch. Plus, there's no need to accessorize with any jewelry - talk about getting two for the price of one!

When Caitlyn took the stage, Kim cupped her mouth to cheer on her stepfather, who was making her first major public appearance at the awards show since announcing her transitioning to a woman during an April tell-all. 

The reality star looked poised as she applauded beside her older sister Kourtney.

That same day, Kim, who is expecting a son with husband Kanye West, showed off her glamorous look in a classic black-and-white selfie.

The Selfish author captioned the alluring Instagram image: 'Tonight.' 

Kim also shared a playful family photo of herself beside her sisters, as well as stepsiblings Brody Jenner, Burt Jenner, Brandon Jenner, and Casey Jenner.

Casey's husband Mike Marino was also in the photo, alongside Brody's girlfriend Kaitlynn Carter and Burt's partner Valerie.

However Brandon's wife Leah Jenner was not at the event, as she is about to give birth to the couple's first child, a girl. 

The OIympian's children have been continuously supportive of their father's decision to transition into a woman. 

On Father's Day Kendall called her 'my hero' praising her bravery. 

And when Caitlyn was first unveiled in June on the cover of Vanity Fair she led the outpouring of love, simply telling her dad 'be free now pretty bird'.

Kim recently told MailOnline that her relationship with Caitlyn has changed since her gender transition.

'It's a different one. We're definitely closer and I understand her a bit better, and her struggle.

'I respect all of her decisions, and I think it's great that she can be so honest and brave and be who she wants to be.' 

The former medal winner - who was known as Bruce Jenner before her transition - came out to the world during an interview with Diane Sawyer in April and later unveiled her new identity with a Vanity Fair cover in June.
