Meghan Trainor's dad used to buy her gel "implants" for her bras.

The 31-year-old pop star - who is married to 'Spy Kids' actor Daryl Sabara and has Riley, four, as well as 21-month-old Barry with him - recently went under the knife to achieve her "dream" breasts but recalled a time when even her father noticed that she was so self-conscious about them that he tried to help her by buying her gel inserts for her bra.

Speaking on the 'Forever Young' podcast, she said: "My dream in life was...since high school, I knew. My dad would even notice. He used to buy me the implants, those gel foam things,that you could get at Victoria's Secret and he came home like 'Look what I got you, buddy' because he knew that I was so lopsided. He was like 'Maybe this will help...' but how embarrassing is that?

"It's totally normal.

"But someday, I was like 'I'm gonna have the boobs of my dreams...' "

The 'All About That Bass' hitmaker always felt as if she "needed" surgery, and after having the surgery as well as also losing more than 60lbs, has admitted that she has finally learned about "nutrition" and wants it to be taught in schools.

"And I knew I needed a lift since day one. They came out saggy, I was raised with saggy boobs. [With pregnancy], I gained the most weight I've ever had, then I lost it all, and I lost even more and now I've finally learned about nutrition which I wish they taught in elementary school. I'm trying to teach my own kids."

But the 'To The Moon' songstress felt confident in her decision to go for a boob job because she didn't even see her breasts as her own as the surgery date drew closer.

She said: "The week before the surgery, I would look at my boobs in the shower and be like 'These aren't even mine anymore. Get them off!' I had a really nice friend who had really nice boobs and she was like 'I got the doctor' and I was like 'I want those!' "So that's always nice when you've seen proof!"
