Peaches - who has a five-month-old son Astala with the musician - took to twitter to tell her followers that she has been busy nursing her new husband after he fell ill.
Peaches wrote: "Tom is sick with flu today! I am making him a lemsip."
The couple got married in Kent, South East England, surrounded by family and friends, including Peaches' father Bob Geldof.
The bride wore three different dresses throughout the day - custom dresses from Dolce & Gabbana and Alberta Ferretti as well as a Marchesa dress for the party.
Talking about her outfits, she tweeted: "My second wedding dress was Dolce & Gabbana! It is the VERY FIRST wedding dress they have EVER custom made for anyone! A piece of history! (sic)"
