Grammy winner Meghan Trainor included a "shoutout" to Mounjaro, which she used "to help me after my 2nd pregnancy. And I'm so glad I did because I feel great" in an Instagram post on Monday, March 31.

Also, like with Ozempic and Wegovy, those who take Mounjaro will likely need to keep taking the medication forever in order to keep the weight off. Mounjaro can be expensive, especially since the FDA has not approved it for those who want to lose weight and don’t have diabetes. That means insurance companies likely won’t cover it.

The “All About That Bass” songstress showed off her slimmed down figure weeks after revealing she underwent a breast augmentation.
