A sneaky Instagram user snapped a shot of the trio while posing for a selfie, and clearly, Michelle, Malia, 15, and Sasha, 12, are enjoying the power couple's performance.
The FLOTUS showed off her toned arms in a simple sleeveless ensemble, while her daughters were also dressed casual for the occasion.
Before the show, Barack Obama's missus dined with friends at restaurant Sunda, where she feasted on signature dishes such as brussels sprout salad.
According to an eyewitness, the first lady sat in the eatery's private event space on the second floor and seemed to be in a great spirits, happily posing for pics with the owner and staff.
This isn't the first time Michelle and her daughters have been snapped at a Beyoncé show. The trio attended the singer's Mrs. Carter Show last summer, and they went to her Atlantic City concert just one year prior.
It's no secret Jay Z and Beyoncé have a long-standing relationship with the Obama family. Back in September 2012, the hip-hop royal couple hosted a $40,000-ticket fundraiser for the Obama campaign at the rapper's 40/40 Club, where Barack thanked "J and B" for their friendship and gushed over the A-list duo.
"Beyoncé could not be a better role model for my girls," the POTUS said before drawing another parallel between himself and pal Jay Z. "We both have daughters and our wives are more popular than we are. So, you know, we've got a little bond there. It's hard but it's OK."
Most recently, the "Irreplaceable" beauty performed at the first lady's 50th birthday bash January. She's also serenaded the political power couple during the president's first inaugural ball in 2009, and she performed at his inauguration ceremony in 2013.
Moreover, Blue Ivy's mama posted a posted a handwritten missive to Michelle on her site in April 2012, calling the mother of two "the ultimate example of a truly strong African American woman."
"She's a caring mother, she's a loving wife, while at the same time, she is the First Lady!" Bey writes. "Michelle, thank you for every single thing that you do for us. I am proud to have my daughter grow up in a world where she has people like you to look up to."
Clearly the admiration is mutual. Stay flawless, you two!
