WWE Superstar Tiffany Stratton is set to take part in her first SummerSlam match Saturday night at MetLife Stadium ... but don't think any nerves are running through the champ -- 'cause she tells TMZ Sports she is "never afraid!!"
We caught up with the WWE Women's Champion out in NYC ahead of her title defense against Jade Cargill ... and it's clear she couldn't be more excited to go out and put on a show.
"I am super excited," she said.
