The mum gave her son a small kiss
In the post, she said: "Let us introduce you to our newest addition... Frederick (Freddie) George Lampard! We are completely in love @franklampard."
The doting mum recently shared a photo from a family vacation where her daughter, Patricia, two, studiously looked at the in-flight safety brochure.
"Safety first," the 42-year-old captioned her post, adding a heart emoji.
And during an appearance on Lorraine on Tuesday, she shared several photos and videos of her children, including one where Patricia appeared to be taking after her father by playing football.
Speaking to Lorraine Kelly, she revealed: "She loves football, I'm not even kidding you! She absolutely loves football…

"Do you know the really pathetic thing though is that [Frank] talks to her like she's a premier league player!
"He tells her off saying, 'No, one, two, one two…' a proper football conversation and I say, 'She's two and a half Frank!' So she doesn't stand a chance, she has to be a footballer!"
On how Patricia is with her new baby brother, Christine said: "She is really good. Is he like her dolly? A little bit, but then she forgets he is there and couldn't care less! But if she hears a little moan she starts singing little songs to him, which we thought was quite sweet.
"But she has been really good actually. She has been a nice big sister so far, but it's early days!"
