The presenting duo got the giggles (and we mean REALLY got the giggles) after Holly made an unusual noise while laughing. Crying with laughter, Phil looked a little confused and asked Holly: "What was that noise?! You've never made that noise before."
We're not sure what was funnier, Phil's reaction or Holly's surprised look on her face!
Holly replied: "I don't know! It just came out!"
Both Holly and Phil could not stop laughing and you know what it's like, they then started tearing up, thanks to their giggles.
And, of course, just when they both managed to calm themselves down, they were played back Holly's laugh and creased up yet again. Phil declared: "I want that as my ring tone!"
"You should have it as your text message," Holly told him.
Oh, you've got to give it a watch!
Holly and Phil's funny moment comes after the pair recently opened up about their close relationship. They have now been presenting alongside each other for over a decade, and chatting with the Loose Women panel, Phil revealed that he and good pal Holly have "never, ever" had a row.
That's pretty impressive, right?
Phil said: "I don't think we do [argue]. I can honestly say, hand on heart, we have never, ever had a row. Honestly." He joked: "She has never pushed me that far."
"We hang out and what's lovely is that my Steph and Holly's Dan get on. All the kids get on..." Phil added. "When we're on holiday and go out for dinner, we don't talk about work. We keep it separate."
Holly agreed, she said: "The fact that we've worked together, we do so many hours together and when we're off in the summer and we choose to spend a lot of time together... we think in the same way. It makes it a lot easier."
