Beyonce Knowles is thrilled her daughter Blue Ivy Carter has a role model like Michelle Obama.

The 'Halo' singer has penned an open letter to the US First Lady, praising her for her achievements and for being ''humble, loving and sincere'' and said she is proud her three-month-old child with husband Jay-Z has someone like Michelle to look up to.

In a posting on, she wrote: ''Michelle is the ultimate Example of a truly strong African American woman. She is a caring mother, she's a loving wife, while at the same time, she is the First Lady!!!!''

''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 ended the handwritten letter with a personal note to the First Lady - who is married to US President Barack Obama.

She wrote: ''Michelle, thank you so much for every single thing that u 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.''
