Melania made it clear there are some things she simply won’t reveal about her husband.

Melania Trump once gave viewers a glimpse into her husband’s sleeping habits during an appearance on Fox News’ The Five. While discussing her memoir, she confirmed that Donald Trump doesn’t sleep much, smiling as she explained that he gets by on relatively little rest.

The conversation took an unexpected turn when co-host Greg Gutfeld asked whether the president wears pajamas. Melania quickly answered, “No.” But when Gutfeld followed up by asking what her husband wears to bed instead, she zipped her lips with a playful gesture, leaving the question unanswered.

Her reaction sparked curiosity because it suggested that, even in a lighthearted television interview, Melania was drawing a clear line around certain details of their private life. Rather than revealing more, she smiled and let the moment speak for itself.

CNN journalist Kaitlan Collins has also described Donald Trump as someone who reportedly stays awake talking during long flights aboard Air Force One. According to her account, his habit of remaining awake can sometimes make it difficult for staff members to get enough rest.

But when it comes to what happens behind closed doors, Melania’s message was simple: some things are better left private.
