The former FLOTUS made the revelation as she discussed her life during an interview with Jimmy Kimmel. During the chat, Michelle said that she and Barack would “fight” over who could use which anecdotes in their books. Michelle released her book ‘Becoming’ last year to critical acclaim.
Barack is expected to release his own soon.
During the interview, she said: “Since my book was first, he lost on all that – all the good stuff.”
Jimmy then asked Michelle about whether there would be a “rift” between her and her husband, former US President Barack Obama if Oprah did not include his book in her book club.
Michelle responded jokingly and said: “It might hurt his feelings but he’ll get over it.”
Michelle also revealed during the interview what it was like being unemployed ahead of the release of her book.
Mr Kimmel asked her what unemployment was like after leaving the White House over a-year-ago.
Michelle joked that the two former heads of state had now become “boring”.
Michelle said: “I was just trying to think of what we’ve been doing but truthfully, we’re boring.

She told her readers of how she warned Barack that he needed to be brought back into the 21st century.
She wrote: “Barack told me, ahead of leaving, that he preferred letter writing.
“I informed Barack that if our relationship was going to work, he’d better get comfortable with the phone.
During an interview with CBS host Gayle King, Michelle also confessed about how her and Barack’s marriage should not be used as an example.
Michelle said: “Young couples think that all they see of us is the fist bump and the love and I’m looking adoringly at his speeches.
“And my view is that we can’t be up here as role models and not be telling people the truth about life and relationships. Marriage is work. Marriage is hard.”
Oprah is best known for her talk show, The Oprah Winfrey Show which is broadcast from Chicago.
The show was the highest-rated television program of its kind in history.
Oprah has also been ranked as the most influential woman in the world.
