Jazz Jennings Shows Off Weight Loss Ahead Of 'I Am Jazz' Season 8 Premiere: 'Looks Amazing'

Jazz Jennings proudly showed off her body transformation in a new social media update.

On Tuesday, the 22-year-old trans activist took to Instagram to share snaps from a music festival she attended with her brother Sander, 24. The siblings did not name the festival.

In the first photo, Jazz stood on the grass beside the lake wearing a matching tie-dyed shirt and skirt and black trainers. She visibly looked thinner compared to how she was in her previous posts.

In the second snap, Jazz flashed a big smile as she posed on the same spot with her brother, who was shirtless and rocking dark genie pants, an intricately designed shawl and a pair of black shoes.

"Had so much fun dancing, singing and vibin' [heart emojis]. Thanks for a great time @sander_jennings," she captioned the post.

Sander immediately responded, "I'm glad I could show you the fest life."

He added, "Had so much fun with you this weekend!!! It's always so amazing to come back together after being far apart for a few months."

Aside from the reunion between the siblings, most fans took notice of Jazz"s weight loss. Many were proud of the reality star for taking her body goals seriously.

"You are looking good girly! Thinning right down. All your hard work is paying off," one wrote.

"You look amazing, Jazz. Way to go," another commented.

"Congratulations on your weight loss, girl. You look amazing," a different user added.

Jazz's post came a week after her family excitedly announced on their new Instagram page the premiere date of "I Am Jazz" Season 8.

Based on an update they shared, the upcoming installment in their hit TLC series will debut on Jan. 24 at 10 p.m. EDT on TLC.

The official synopsis released via Variety last month revealed that the eighth installment will feature Jazz's life after moving out of their home. It will show her big move to enter college and her struggles to live independently.

However, since cameras are not allowed on the Harvard campus, fans will only get a glimpse of her college life. The series will focus more on her return to Florida after surviving her first year at the prestigious school.
