“So anything that'll help me age backward, I’m into it,” Trainor, 31, explained. Expressing her enthusiasm, the pop diva said, “I just learned about the NADs [food supplement capsules]. I was like, ‘Make me Hailey Bieber, I'll do it, I'll take it.' [...] I’m trying all the things. I love a doctor explaining stuff to me.”

The singer who first rose to fame singing about embracing her curves, going viral with witty lines such as, “You know I won’t be no stick-figure, silicone Barbie doll,” and her outspoken body positivity, made heads turn after she debuted her weight loss on Instagram.

The singer, who said she is “in love” with the results, explained in an Instagram video why she decided to undergo the procedure. With touring, working, and “mommying” her two sons, Riley, 4, and 20-month-old Barry, she “decided to do something” just for herself during this “super busy” phase of her life.
