The married couple were the picture of wedded bliss as they cuddled up to go punting on the River Cam on Wednesday (24 June).
Mark wrapped his arms around Michelle as they enjoyed the sunshine and scenery during their romantic trip up the river.
A source said: They looked really happy together and were cuddling in the punt."
They were also pictured holding hands as they walked around the town and stopping off for cold drinks at a Prezzo restaurant.
Michelle, 28, was looking as gorgeous as ever in her denim playsuit and white T-shirt that highlighted her a-mazing tan. No doubt thanks to that honeymoon in the Maldives and Dubai!
It was one month ago that Michelle walked down the aisle at St Mary's Church in Bury St Edmonds, Suffolk to marry ex-TOWIE star Mark.
She later said: " The one word I can use to describe this whole month is magical. So happy and so grateful. Here's to the next chapter."
Next up for Michelle will be a role in BBC drama Our Girl as she steps in to replace EastEnders' Lacey Turner, while Mark is busy with his Heart FM radio show.
