The WWE built up - SummerSlam 2021 - to be a massive pay-per-view event with John Cena in the main event, challenging Roman Reigns for the Universal Championship.  

Ahead of the event, WWE Hall of Fame wrestler Nikki Bella, who just happens to be Cena's ex-fiancé, shared her enthusiasm on Instagram by posting photos of herself announcing her arrival in Las Vegas, and attending a WWE after party event decked out in a skimpy metallic mini dress.  

But by the end of the night, Bella revealed, via Instagram, that she wasn't allowed to attend the sold out event at Allegiant Stadium.

The retired wrestler, 37, turned more than a few heads when she hit the red carpet at the after party held at Delano Las Vegas inside Mandalay Bay Resort and Casino.

The skimpy number, which was worn over a skimpy slip, could barely cover up her womanly curves.

She rounded out her ensemble with open-toe heels and her raven tresses styled long, straight, and with a part in the middle.

At one point she she shared the spotlight of the red carpet alongside WWE wrestler Eva Marie, who shined under the bright lights in a sequin mini dress and bold red locks.
