It's unclear when Trump will make a public appearance, but Grisham insisted Friday, "She is fine, she's doing great".
Stephanie Grisham, the first lady's communications director, told ABC News that the first lady will be skipping the trips.
First lady Melania Trump isn't joining her husband at the G7 summit in Quebec this week.
Mrs. Trump's decision not to go to Quebec is a departure from past year, when she made an worldwide summit debut at the G7 meeting in Italy and followed up at the forum of G20 industrialized and developing nations in Germany.
The White House did not immediately respond to a request for comment from TheWrap. "The First Lady looks forward to a full recovery so she can continue her work on behalf of children everywhere".
Parliament ousts Spain PM, replaced by Socialist leader Pedro Sanchez
In parliament Thursday, Sanchez presented his case that Rajoy must go because Spain "is sick and exhausted of serial corruption". Rajoy told the Spanish parliament that he was proud of his record as prime minister in brief remarks ahead of the vote.
She posted: "I see the media is working overtime speculating where I am & what I'm doing".
The White House has released little information about her since the operation and Melania herself is under no public obligation to disclose what she has been doing.
So, where could the first lady be? "She's looking at us right there".
However, the first lady's office knocked down the report as 'false'.
The blog Showbiz411 quoted a source as saying the reason the first lady hasn't been seen in public in 21 days is because her mother, Amalija Knavs, is very ill.
Melania's absence led to many people making widespread rumours and conspiracy theories.
