Made in Chelsea's Hugo Taylor will also appear alongside Flanagan in the show, according to The Sun.
Meanwhile, the other celebrity team-ups on the summer series will be Celebrity Big Brother stars Pete Burns and John McCririck, and Geordie Shore's Gaz Beadle and Charlotte Crosby.
The stars will be given a budget of £12,000 and 21 days to organise the wedding.
A Channel 5 spokesman said: "The confirmed line-up of celebrity pairings looks amongst the series' most provocative.
"The summer series will see these catastrophic couplings wreaking havoc and mayhem as they try to pull off the wedding of a lifetime."
Katie Price and Duncan James were previously attached to star in the series, but they both dropped out last month.
