Anna, 34, who's best known for her appearances on This Morning, welcomed her first child on 27th September with her husband Alex Di Pasquale.
The happy new parents have named their beautiful baby boy Enzo, and confirmed he weighs a healthy 7lbs 4oz.
We're sure the birth will come as a bit of a relief for the new parents, as Enzo's arrival was 11 days past his due date! Anna recently took to Instagram to talk about her 'very testing' week waiting for labour.
This week has been a very testing one for me personally as I'm a week overdue ð‘¶ it's been super important for me to practice what I preach, all my training and techniques are coming into play and I'm finding a new love and respect for #breathing & #visualisation to help with keeping calm & focused & unhelpful #anxiety at bay. I'll be going into these techniques in my book too which you can pre-order @bloomsburypublishing ð“ð“– #anxietybusting
Since the new arrival, Anna has shared her happy news on social media, along with a picture of baby Enzo.
While staying in the Princess Alexandra Hospital NHS Trust in Harlow, Essex, the new mum shared a photo of her smiling with her baby, saying: 'This happened this week. Best thing we ever did @adpfitness 💙 we got a little boy'
Anna revealed her pregnancy in March this year in an Instagram video, saying: 'Really chuffed to tell you that I'm expecting a little baby. Phew....it's been a rough 12 weeks trying to keep it schtuum!
'Very happy although as I'm finding out already, pregnancy and #anxiety is a whole new ball game! I'm going to be shedding some light on it, and of course my usual videos over the coming months #anxietybusting #babynews.'
We first got a glimpse of Anna's baby bump in April, when she took to the red carpet at the premiere of The Jungle Book with her husband.
Anna married her fitness guru hubby Alex in 2015. Writing in her blog post at the time, she said: 'I can't believe it... me... marriage... yep it's really happening.'
'This October I'm embarking on the next stage of my life and after 34 years, am changing from a ‘Miss' to a ‘Mrs' gulp]'
'After what has been a whirlwind engagement (after a very heartfelt proposal), my Mr and I are to get hitched at my family village church in Hertfordshire, surrounded by our nearest and dearest, in what will be a small, yet (I hope) perfect day.'
Anna has worked on Citv, Big Brother's Bit On The Side, GMTV and Daybreak before training as a counsellor. She regularly appears on This Morning as an agony aunt and is an official celebrity ambassador for the charity Mind.
Congratulations to the new parents!
