37-year-old Jones married Jackson in a secret ceremony at the Mayfair Library in London on Monday 6 October before celebrating with close friends and family at a reception near Tower Bridge.
"They are absolutely over the moon," a source told the Mirror. "All their friends and family are delighted for them. It might seem to have happened incredibly quickly to outsiders, given that they only had a few weeks to plan the entire day, but they couldn't be happier.
Jackson has previously shared a picture of her engagement ring as well as an image of her wearing a gold dress at the wedding reception with the caption, "Mrs Jackson Jones."
Clearly she was keen to show off another highlight from her big day, too. The cake, complete with "delicious chocolate and vanilla tiers decorated with all edible flowers!" looked delicious...
Just have to give a big shout out/thank you to @wkndkitchen and #FionaCairns for our lovely lush wedding cake. Delicious chocolate and vanilla tiers decorated with all edible flowers! It truly went down a treat! 💋🍰🌸🌹🌻👌
