Ellen DeGeneres Helps Michelle Obama Sell Copies of Her Memoir at Costco

Ellen DeGeneres helped Michelle Obama sell copies of her new memoir, Becoming, at Costco as only Ellen could--by embarrassing the former First Lady in front of customers. “Michelle Obama, Michelle Obama wrote a book,” DeGeneres sings in a segment on Thursday's Ellen while sitting next to Obama and serenading her inside the store. “She mentions Oprah [Winfrey] several times and me only once!” It seems DeGeneres just couldn't let that slight go, later adding, "Michelle wrote a book mentioning Oprah too many times, but me only once. One time she mentions me, but only once!” Ellen and Michelle have a long history of cracking each other up. They famously shopped at CVS together in 2016 and engaged in a push-up contest in 2012--which Michelle won. [People]
