It was recently claimed that the pair's friendship was cooling behind-the-scenes at This Morning - an allegation that ITV denied.
During a press conference for the next series of Dancing On Ice on Monday evening, Holly opened up about how long she's been working alongside Phil.
She said: "Phil and I met on this show. There’s a lot of history. You’re going to set me off," as she began getting emotional.
"My kids really love the show as well. I get quite emotional thinking about it, that all of them were carried in my tummy on this show and when we finished I always went off and had the babies.
Phil and I met on this show. There’s a lot of history.
"So now it’s really nice because they love it and I tend to split it, I bring one of them each week, they come for the whole day and sit through the rehearsals.
"It’s really nice. It’s a real family show."
In a separate interview with BBC's Newsbeat, the pair hit back at suggestions of a rift.
Holly said: "You couldn’t do the amount of hours of TV that we do with each other without getting on."
Phil added: "We have such a laugh. We’re best mates, she’s like the sister I never had. I just adore working with her, she’s just perfect."
It comes after ITV called reports Phil had been 'feuding' with his co-stars "deeply disappointing and unfair".
According to The Sun, a source claimed Holly and Phil's relationship has "become strained in recent months".
It was even claimed that Ruth Langsford had made an official complaint against Phil, 57.
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."
