On Jimmy Kimmel live Mr Obama joking claimed he is afraid of his wife and younger daughter.
He said: “The reason is Sasha is a mini Michelle, and I’m afraid of Michelle.
“And Sasha, having seen that, basically has the same look, the same attitude.”
However Mr Obama said his older daughter, Malia, has picked up more of his personality traits.

He commented: “Malia is more like me temperamentally.
“We call ourselves ‘The Long Faces,’ because [Malia’s] face is more shaped like mine, and ‘The Round Faces’ are Michelle and Sasha.
“The Round Faces are a fiercer tribe.
“We’re like the vegetarians, the gatherers, and they’re the hunters.
Michelle and Barack Obama have been married since 1992
Between January 2009 and January 2017 Ms Obama served as first lady of the United States.
A Promised Land is expected to be the best-selling presidential memoir of all time.
Mr Obama had planned to cover both his presidencies in the 701-page long book, but only got as far as 2011.
The rest of his time in office will be covered by a subsequent work.
Speaking to Mr Kimmel Mr Obama revealed his children have yet to read his book.
He said: “Their attitude is, ‘We’ve got better things to do than to read your boring rants and raves’.
“They’ve promised at some point in they will.”
In his memoir Mr Obama described a number of his fellow world leaders including former David Cameron.
Writing about the former British Prime Minister he said: “In his early forties, with a youthful appearance and a studied informality (at every international summit, the first thing he’d do was take off his jacket and loosen his tie), the Eton-educated Cameron possessed an impressive command of the issues, a facility with language, and the easy confidence of someone who’d never been pressed too hard by life.
“I liked him personally, even when we butted heads, and for the next six years he’d prove to be a willing partner on a host of international issues, from climate change (he believed in the science) to human rights (he supported marriage equality) to aid for developing countries).”
