The BBC has managed to wrangle Spencer Matthews and members of S Club 7 and The Saturdays to step into a boxing ring and actually fight for an upcoming TV special. In a format that sounds way too good to be true, four stars will go through extensive training for a special Sport Relief programme called — you guessed it — Celebrity Boxing! And the matches are pretty exciting too! In the second bout, two of pop’s all-time biggest groups collide when Hannah Spearritt from S Club 7 squares off with Vanessa White from The Saturdays in a bout that will surely have viewers All Fired Up. Our advice for Hannah is Don’t Stop Movin’, and definitely rely on some of the scrapping you learned from tangling with the Taylor family on EastEnders. Celebrity Boxing will be airing as part of the Sport Relief telethon on Friday, March 23 on BBC One, so llllllllllllllet’s get ready to rumble!
