According to The Sun, daytime boss Emma Gormley reportedly said Ben was her top choice for a possible replacement if Phil ever leaves the show.
However, a spokesperson for ITV told us that the claims are "untrue".
According to The Sun, eight ITV presenters described the environment at This Morning as "toxic".
However, in a statement, an ITV spokesperson said: "It’s deeply disappointing and unfair for Phillip to be the target of this sort of malicious gossip.
"Phillip is a much respected broadcaster and colleague and this is absolutely not a description of This Morning that we recognise.
"Holly and Phil are great friends both on and off screen and are popular among viewers and colleagues alike."
It’s deeply disappointing and unfair for Phillip to be the target of this sort of malicious gossip.
Meanwhile, editor of This Morning, Martin Frizell, told Entertainment Daily: "I spend hundreds of days a year in their company and what you see is what you get, a genuine friendship from a couple who are both spontaneously funny and professional.
"We have the smartest viewers watching telly and believe me they would be the first to notice any issues - they haven’t because there are none."
Holly and Phil addressed the reports at Monday evening's Dancing On Ice launch.
Speaking to BBC's Newsbeat, Holly said: "You couldn’t do the amount of hours of TV that we do with each other without getting on."
Phil described Holly as "perfect" and insisted they're "best mates", adding: "We have such a laugh. She’s like the sister I never had. I just adore working with her."
