In an interview with OK! at The Pride of Britain Awards, Phillip said he was hoping to visit Holly and meet her new arrival later this week.
He said: "I haven't seen him yet - I think we're going towards the end of the week. She's been sending lots and lots of pictures.
"He's fabulous and she looks gorgeous."
Holly gave birth to Chester William on September 19. She is also mum to Harry, five, and Belle, three, with husband Dan Baldwin.
The new mum worked pretty much straight up to her due date, before Amanda Holden took over her duties on the This Morning sofa.
Soon after Chester's birth, Holly rang Amanda and Phillip on air to share her happy news.
She told the pair: "I'm really good and really happy. I started having contractions about nine in the morning and they kind of lasted all day. He arrived about 7.20pm.
"It was very different from the other two. I had a water birth, which I've never thought of doing. That was amazing. He was a really big boy - 8lb 12oz!
"He's so delicious. I can't stop looking at him. He is perfect."
