Caitlyn Jenner lets loose at Pride 2015 event

Before her transition, she vowed to use her status to help members of the LGBT (lesbian, gay, bisexual and transsexual) community, and it looks like Caitlyn Jenner has kept her promise.

The former Olympian has lent her support to the Pride campaign, with an appearance at a New York City hotel to celebrate New York's 2015 Gay Pride Parade.

The 65-year-old step-parent of Kim Kardashian joined scores of revellers at her bash, which was her first public appearance since making her debut on the cover of Vanity Fair magazine.

For the event, held at the PH-D Rooftop Lounge in the Dream Downtown Hotel, she opted for a glammed up look of white top and skirt. She wore her hair in loose waves and natural make-up.

She also used the event as an opportunity to film scenes for her forthcoming eight-part reality E! Special I Am Cait. Jenner made sure to make her presence known at the party and could be seen letting loose mingling with the crowd. She made sure not to miss a moment by capturing pictures on her mobile phone.

A fan shared an image of the luminary with her thumb up smiling from ear to ear.

The caption read, "Caitlyn showed up for pride ?? #thumbsup #nycpride #candiscayne #transgender #transmutation #nowayrose #caitlynjenner.''

According to US Weekly, Jenner stepped out with a group of girlfriends, including transsexual actress Candis Cayne from ABC's prime time drama Dirty Sexy Money, Elementary.

The appearance comes days after a new I Am Cait promo was released showing the former partner of Kris Jenner embracing daughter Kylie.

"We're going to talk about everything," she promises. "We're going to do a lot of fun things for the first time. We're going to go shopping for the first time. Maybe even some boy stuff, like ride a motorcycle — because girls do that, too!"

In April, the gold-medallist put an end to months of speculation about his increasingly feminine appearance during an ABC two-hour special with Diane Sawyer by boldly declaring: "For all intents and purposes, I am a woman. My brain is much more female than it is male. That's what my soul is. Bruce lives a lie. She is not a lie. I can't do it anymore," he explained.
