Marvin Humes and Rochelle Wiseman plan to marry within 10 weeks.

The couple - who got engaged on New Year's Eve (31.12.11) - have reportedly decided to coincide their nuptials with their birthdays, as Rochelle turns 23 on March 21, three days after the JLS hunk celebrates turning 27.

A source told the Daily Star newspaper: "After getting engaged this Christmas, Rochelle and Marvin didn't waste any time in thinking about dates. They knew they didn't want a long engagement that dragged on for months.

"After deciding they wanted to be married by summer, they then thought it would be a good idea to coincide the big day with their two birthdays on March 18 and March 21."

The Saturdays singer Rochelle is said to be particularly excited by the plan.

The source added: "Rochelle has been telling her pals how excited she is and that she loves the birthday idea. She thinks combining the events will make it the most amazing three-way Celebration ever."

The couple announced they had got engaged on New Year's Eve (31.12.11) during a holiday to Antigua via a post on Rochelle's twitter page.

Accompanied by a photo of the pair toasting their engagement with two glasses of champagne, the 22-year-old pop beauty tweeted: "Its official Marvin proposed 2me 2day, wanted 2 tell u b4 some1 else did! SO excited 2 b Mrs Humes. X (sic)"

Marvin and Rochelle first started dating in March 2010 after falling for each other on the showbiz circuit.

However, they separated in November of the same year due to work pressures but they rekindled their romance in January 2011 and soon moved back in with one another.
