ITV2 are reportedly struggling to sign up groups for series two of The Big Reunion.
The first shows this Spring saw reunions between a number of 90s and 00s groups, including Five, Atomic Kitten and Liberty X.
The reunited groups went on to secure an arena tour which will kick off in May, but the success hasn't seen other groups jumping to take in future series.
According to the Daily Star, girl groups Eternal and All Saints have already turned down offers.
A source told the tabloid: “Shaznay isn’t interested and it would take a miracle to get Eternal back together.”
The newspaper reports that bosses are current in talks with 90s boy group Bad Boys Inc and Big Brovas.
However S Club 7 could be amongst the line up, becoming the favourites to take part in the secon series.
The group's Rachel Stevens teased: "We are all up for doing something. We just need to make sure it’s the right thing."
