As said in the 'Royal Baby 2' thread, when Kate was pregnant with George, ITV made both 'It's and Boy' and 'It's a Girl' idents so that is where this ident comes from (and is why the ident is same as 'Boy')
I didn't know where to put this, but has anybody seen the 'Come in to itv this autumn' teaser trails?
I've just spotted this one during an odd late night Tipping Point (it was on in the background - honest!)
Sorry for the mobile capture...
