Michelle Obama has a big admirer in Beyonce. In fact, the superstar is such a fan of the First Lady, she sings Obama's praises in an open, hand-written letter, which was just published on her newly re-launched website.

"No matter the pressure, and the stress of being under the microscope -- she's humble, loving, and sincere. She builds and nurtures her family, while also looking out for so many millions in so many ways," Beyonce gushed. "I am proud to have my daughter grow up in a world where she has people like you to look up to," Bey added, praising Michelle as role model for her 3-month-old girl, Blue Ivy.

The Obamas and Beyonce have been building a relationship for years. After Bey sang at the President's inaugural ball back in 2009, she teamed up with First Lady Michelle Obama to help promote her Let's Move! campaign against childhood obesity. Bey has since designed merchandise for President Obama's reelection campaign.
