The Saturdays Rochelle and Marvin from JLS to marry in March

Rochelle Wiseman from the girl band the Saturdays and Marvin Humes from JLS have announced their engagement during their holiday in Antigua.

Rochelle was presented with an enormous heart shaped engagement ring surrounded by smaller round diamonds (pictured), which cost Humes £45,500 from the exclusive London jewellers Boodles.

The couple first began dating in early 2010, and it was reported back in July that Marvin was planning a romantic New Year's proposal after he booked an appointment at Tiffany and Co.

They only got engaged on Saturday but it seems they are planning on marrying in March. They are eager to tie the knot in just ten weeks time in order for their big day to coincide with their birthdays.

Rochelle will be 23 on the March 21st and Marvin will celebrate his 27th birthday a few days earlier on March 18th. The couple didn't want a long engagement that dragged on for months and think it is the perfect excuse to have one huge party.
