Photos: WOW: Michelle & Sasha Obama caught in fan's selfie @ Jay-Z & Beyoncé 's concert in Chicago

An eagle-eyed fan has snapped a selfie with Michelle and Sasha Obama as they attended a Beyoncé and Jay-Z concert in Chicago on thursday night.

Yesenia Herrera was standing in front of the first family at Soldier Field when she whipped out her cell phone and took a selfie - capturing Mrs Obama and her younger daughter in the background.

Michelle, who was in the city to hold a Democrat fundraiser, and 13-year-old Sasha were also at the concert with Sasha's big sister, Malia, 16.

Herrera, a model from Chicago, then shared the image to Instagram - no doubt to the chagrin of Michelle Obama, who has previously complained about images of her daughters being shared.

In an interview with People magazine in December, Michelle Obama revealed that her daughters are big fans of her music.

'They love Jay Z. They love Beyoncé. Sasha is still a One Direction fan, although I think Malia has become a little less into boy bands,' Mrs Obama said in a joint interview for People Magazine.

'They've gotten to know Beyonce, and she has always been very sweet to them,' Mr Obama added

In January, Beyoncé performed for Michelle Obama's 50th birthday party at the White House.

She performed hits, including Single Ladies, and was joined by Stevie Wonder in front of 300 guests.
Don't we just love this first lady? Michelle Obama really rocks!!!
