Rachel Bloom no longer has heavy boobs.

The "Crazy Ex-Girlfriend" star had breast reduction surgery recently, sharing the news on social media. Bloom, 34, explained that her decision to have a reduction was due to her breasts changing drastically after she got pregnant and then started nursing.

Not only did they grow in size and texture, but Bloom’s boobs also caused neck pain and other ailments.

"I started to get underboob rashes, shoulder grooving (when your bra strap digs into your skin), neck issues and night sweats (I couldn’t fall asleep unless I had a pillow in BETWEEN my breasts)," the actress wrote on Instagram.

Bloom said her breasts were normally a DD/DDD cup size but that they jumped to a G after she got pregnant.

She went on to share that she met with three different doctors before deciding on the one she was most comfortable with performing the reduction surgery.
