No Bra, No Problem: Beyonce Wears a Completely Unbuttoned Shirt to Lunch

Beyonce stepped out for lunch with Jay Z at Gracias Madre -- a vegan Mexican restaurant in West Hollywood, Calif. -- on Tuesday, where her denim-on-denim outfit definitely turned plenty of heads. The 33-year-old "Single Ladies" singer knotted her button-up to show off her toned stomach, but most strikingly, left the sexy shirt completely unbuttoned.

Seriously, how is that top staying in place?!

On another note, it's good to see Beyonce and Jay Z sticking to their healthier eating habits, especially since the singing superstar and her trainer Marco Borges announced their partnership to launch the 22 Days Nutrition plant-based home delivery meal service earlier this month.
