The couple announced they had welcomed their first child together last week and they seem to be soaking up every minute of the newborn baby bubble.
Roxy flashed her legs in a short navy buttoned dress just seven days after giving birth to her baby girl.
She complemented the outfit with a pair of black lace up boots while she tied her blonde locks back in messy space buns.
The pair looked in good spirits as they headed to a local espresso bar to grab some takeout coffees and a box of cake.

Roxy gave birth at the Lindo Wing at St Mary's in London and was seen leaving the private hospital with Jack last week.
Taking to Instagram the following day, Jack admitted the experience was both 'utterly overwhelming' and 'joyous' in ways he 'couldn't have imagined'.

He continued: 'Having vowed I’d never be that guy I am now 100% going to be the parent that shows everyone endless pictures of their kid. I also wore sketchers to hospital, I think I must accept I am a full blown dad now.
'Name wise after this weekend I think ‘rice, rice, baby’ has a nice ring to it.'
