Frankie and Wayne Bridge welcomed baby son Carter at 12.04am on 15th August.
Their second son weighed 7lb 2oz.
The Saturdays songstress announced the news on Twitter, writing: “Our gorgeous baby boy Carter Bridge was born this morning.
“He is absolutely perfect - Parker is so excited to be a big brother!”
However, while Parker was excited, she has since admitted that her little boy was quite bewildered at first.
Speaking with OK! magazine, the 26-year-old said: "Parker didn’t really react to Carter at first and I don’t think he really knows what’s going on yet.”
However, despite that awkward first meeting, it seems as if little Parker is loving life as a big brother.
Revealing how her eldest son has adapted to his role, Frankie said happily: “He has started sitting next to him and stroking his head.
"He also loves giving him his teddies!
“It’s lovely to see and he definitely seems excited to be a big brother."
N’aww - that sounds adorable, doesn’t it?
