'It's Serious!' Jazz Jennings 'Beats' Herself Up Over Weight Gain Amid Drug Scandal

Jazz Jennings learned on this week's I Am Jazz that she might not be able to undergo gender confirmation surgery because of her weight gain. The transgender activist turned to Twitter to express her dismay over the bad news.

"I need to lose 30 pounds to get the bottom surgery," she tweeted. "I knew my weight gain was an issue, but I didn't realize it would affect something that I've wanted my entire life. This is serious."

This season delves into Jennings' insecurity over her weight gain, as she said in a trailer, "My eating habits are beyond my control. I really feel like a beached whale."

The weight gain comes amid Jennings getting busted swapping cash for an herb-like substance. RadarOnline.com obtained exclusive photos of Jennings, 17, riding her bike to Poinciana Park in Coral Springs, Florida on December 6. A man, whose identity has been protected pending comment, parked his car in the lot.

"She parked her bike next to his car," an onlooker exclusively told RadarOnline.com. "He was leaning on the front of his car and she walked over to where he was. As she reached into her purse, you could see his open palm containing a substance of some sort."

As she gave the man a handshake he "dropped the bag into her purse while taking the money out of her hand." "She immediately walked around the car and went back to her bike," the source said once the 10-second exchange was complete. "She seemed more concerned about getting it done than seeing if other people were looking."
