Not a bad week for Beyonce.
Over the weekend, she took part in First Lady Michelle Obama's 50th birthday celebration. She posted the above picture (with First Dog Sunny) on her Tumblr account.
She performed Single Ladies and Irreplaceable and looked AMAZING!
And, in an announcement today, Beyonce has been added to the list of performers for Sunday night's Grammy Awards. She'll reportedly perform with hubby Jay Z.
