Rochelle Wiseman and Marvin Humes, who first began dating in March 2010, are on holiday in Antigua.

It was reported back in July that Marvin Humes was planning a romantic New Year’s proposal after he booked an appointment at Tiffany and Co.

The couple rekindled their relationship in January and moved in together following a two month separation.

They began dating in March the year before after meeting a number of times at awards shows and concerts.

Shortly before their brief split, Marvin Humes said in an interview: “I wouldn’t be with her if she wasn’t The One. I don’t believe in being with someone if you don’t believe they couldn’t be that person.”
