Holly, 38, was appearing alongside The Chase's Bradley Walsh to promote their BBC One Christmas show, Take Off With Bradley and Holly.
Interviewed by Patrick Kielty and Strictly Come Dancing's Alex Scott, Patrick began his awkward question to Holly by saying there had been a lot of talk about in the press about "difficult" co-hosts, and he just wanted to ask one question.
Holly looked shocked, and said: "Oh!"
But Patrick then turned it around and said instead: "What makes Bradley such a nightmare to work with?"
Holly regained her composure and joked: "He's a complete nightmare because he never knows what's going on. Normally with Phil I can sit back a bit and relax."
Because Phil's a professional!
"Because Phil's a professional!" Patrick interjected.
"Phil's a professional," she continued, and pointed to Bradley, "this one comes in and is like 'right the rules are this, go on H you tell them!' And I'm like 'ahh', basically I have to do my homework."Phil and Holly have been dogged by rumours of a feud, ever since a report in The Sun claimed that their relationship had soured.
A source alleged that 'jealousy over her I'm A Celebrity Bafta success' was to blame.
Phil also hit back at the claims.
