Taking to Twitter yesterday (21 June), the actress paid tribute to her partner with a sweet post on the social media site. She tweeted: "Happy First Fathers Day @TP_PTfitness - we love you so much!!! Love Me and Alfie xx."
And along with her tweet, Catherine made sure to post a photo of Tom and Alfie together, capturing a sweet 'father and son' moment between the pair.
Can you get any cuter?!?!
In her black and white snap, Tom and Alfie are pictured laying in bed alongside each other. While Tom is staring at his beautiful baby boy, little Alfie looks just gorgeous as he looks back at his dad, hand in mouth and rocking his nappy.
Tom, meanwhile, shared the same photo, telling followers: "My first #FathersDay. Proud and honoured to be part of the club."
Earlier this year in March, Catherine and Tom welcomed son Alfie, becoming parents for the first time. Shortly after his arrival, Catherine tweeted: "We made a wish and you came true. Welcome Alfie James Pitfield. We love you beyond words @TP_PTfitness #Besotted."
Since then, Catherine has shared a slew of pictures of Alfie for fans to see. Our personal fave is this very cute photo of Alfie rocking a baby grow that reads: "I'm cute, Mummy's cute and Daddy's lucky."
Alongside her photo of Alfie, Catherine joked: "So young, yet so wise... #alfiesays ;-)."
Catherine first announced she and Tom were set to become parents in September last year. Shortly after announcing their baby joy, the couple revealed they are engaged.
