Barack Obama made a surprise appearance at Michelle Obama’s book tour in Washington, comparing himself to Jay-Z at a Beyoncé concert. The former president showed up with a bouquet of flowers during the promotional event for his wife’s memoir, “Becoming,” in the nation’s capital on Saturday night. “This is like – you know when Jay-Z comes out during the Beyoncé concert? … Like, Crazy in Love?” he said, referring to instances when the rapper appears at his wife’s concerts during performances of her famous song. “It’s the same thing. It’s just a little sample to enhance the concert.”. First Lady Michelle Obama and the Queen have sore feet in common. The Obamas are the most beautiful family in the world in my book, Those Obamas, their grandmother is as stately as the queen of London. (Courtesy photo)
