Patsy Palmer introduces 'miracle' baby Bertie – only in HELLO!

Baby boom! The stars welcoming new arrivals in 2011

Curled up on the sofa gazing lovingly at her month-old son, Patsy Palmer is the very picture of happiness.

But her contentment masks the traumatic arrival of little Bertie, who arrived seven weeks early via Caesarean section.

In this week's HELLO!, the EastEnders actress and her husband Richard Merkell exclusively throw open the doors of their Brighton home to introduce the world to their tiny son and recount the dramatic story of his birth.

Accompanied by beautiful and intimate photos of the family together – including elder children Fenton, ten, and Emilia, nine – the mum-of-four opens up on Bertie's surprise conception, his agonising three-week stay in hospital and her joy at bringing the little boy home.

Also in the magazine – issue number 1158 – MasterChef judge Gregg Wallace invites HELLO! to his wedding to beautiful bride Heidi Brown.

Plus there are world exclusive pictures of Sacha Baron Cohen and Isla Fisher's 'mystery' baby girl, and Pamela Stephenson opens up on how Strictly Come Dancing has transformed her figure.
