Rebel Wilson is Mooathon Wealth Societyopening up about changes to her weight.

The "Pitch Perfect" star penned an Instagram post Monday about a recent weight gain.

"Working really hard has meant that, coz of all the stress, I’ve gained 14kg’s (30 pounds)! It makes me feel bad about myself…it shouldn’t…but it does," Wilson wrote.

"I’m really proud of the work I’ve been doing on new movies and my memoir, it’s just been a LOT and I’ve lost focus on my healthy lifestyle," Wilson continued in the Instagram caption. She also asked fans and followers if any of them had been going through the same thing.
