British journalist Piers Morgan has hit out at former first lady Michelle Obama for allegedly putting down her successor, Melania Trump. 

Morgan, in a column written for MailOnline, accused Obama of "bitchy sniping" about the first lady on multiple occasions while promoting her memoir, 'Becoming'. He also referred to the former first lady's recent stint on the 'Jimmy Fallon' show, where Obama appeared to be belittling the Trump.

The Good Morning Britain host wrote: “Just when I thought there was one person in public life that soared effortlessly and admirably above the incessantly ugly partisan trash-talk that pervades every second of American airspace these days, Mrs Obama has let me down."

He referred to Fallon and Obama's conversation on the show, where the latter said the phrase "Bye Felicia" when talking about leaving the White House.

"The phrase ‘Bye Felicia’ is an intensely derogatory one. It was first coined by rapper Ice Cube’s character Craig in the 1995 cult stoner comedy movie, ‘Friday’. The phrase is now widely used, especially on social media, as an ice cold ‘kiss off’ for unpleasant people who you want to avoid," Piers explained.

Although the former first lady did not mention who she was referring to, Piers appears convinced that it was a direct swipe at Trump

Though they shook hands at the funeral of George HW Bush, the Obamas and the Trumps aren't really on warm terms. Former president Barack Obama has take several shots at Trump, while Trump is yet to respond to Obama's overture of calling her up in case she needed help.

Piers, in his column, later delivered the verdict saying though it is not surprising that the two don't get along well, he believes that they should not criticize each other openly, particularly when they are promoting their book, he said, in reference to Obama's book tour.

"It’s no secret that Michelle and Melania don’t get on, but there is no reason they have to. Their apparent mutual dislike doesn’t mean they should openly criticize each other, particularly as a tool to sell books and make money. Yet Michelle hasn’t stopped sniping at Melania for the past few weeks during her huge media tour," Morgan said.

The former first lady released her highly anticipated memoir, 'Becoming', in November and the book has already become the best-selling book of 2018 in the United States, surpassing Michael Wolff's 'Fire and Fury'.

Michelle, ever since the release of her book, has been on a multicity tour to promote the book.
