"FIRST full day as a married man!! Wow! Very blessed to be married Mrs @ShaunaMuamba #Happiness," he wrote on his Twitter account @fmuamba.
His new bride also tweeted news of the happy day. "Officially Mrs Shauna Muamba. Thank you all for your love and support," she wrote.
The Daily Mail newspaper on Monday said that Muamba, 24, and 27-year-old Magunda tied the knot at a castle in Cheshire, northwest England, on Saturday, and said that former Arsenal and France striker Thierry Henry was his best man.
Muamba collapsed during an FA Cup tie between his club Bolton Wanderers and Tottenham Hotspur at White Hart Lane seven months ago.
The Democratic Republic of Congo-born midfielder was effectively dead for 78 minutes but was brought back to life after shocks from a defibrillator got his heart beating again.
Despite his recovery, he was forced to retire from professional football in August.
