You can learn a lot about someone by looking through their bag. Of course, you should never actually dig through someone's handbag. However, if someone is willing to reveal their must-haves, it's always fascinating to learn which products are their everyday essentials. Meghan Trainor has shared her favorite makeup, hair care, and skincare products that she carries everyday along with her favorite snack, Quaker Rice Cakes.

The singer told E!, "I was raised on Quaker Rice Cakes and White Cheddar is my favorite flavor. Now, I'm now doing a partnership with Quaker Oats! Check out my Instagram and TikTok pages this month to see the delicious recipes we're creating together." She also carries a TikTok-famous foundation, a root touch-up essential, and her favorite budget-friendly beauty find. 

The Quaker White Cheddar rice cakes have been Meghan's favorite since she was a little kid. This bundle has six packs of rice cakes in White Cheddar, Lightly Salted, and Everything flavors. This trio has 5-star Amazon reviews.

The singer selected this Maybelline mascara as her go-to drugstore beauty item and it comes in three versatile shades.

This top-seller has 5,700+ 5-star Ulta reviews and 29,200+ 5-star Amazon reviews, with one shopper raving, "Honestly I've purchased mascara that costs 10 times more than this. This mascara goes on clean and smooth without clumps. I don't think I will ever buy another mascara. This mascara is been around forever. I love it and don't feel like I'm being frugal. It's so good and consistent each time I open a new tube!"
