The former First Lady divulged about her husband's bedtime habits while promoting her new memoir Melania on Fox News' panel show, The Five.

Host Greg Gutfeld asked Melania whether her 78-year-old husband ever sleeps, to which she responded, "He doesn't sleep much."

Gutfeld followed up by asking if the former president wears pyjamas, to which Melania laughed and answered "No".

"What does he wear when he sleeps, Melania?" Gutfeld asked, to which Melania gestured fingers zipping across her mouth, indicating she wouldn't be commenting further.
