Pregnant former Spice Girl Melanie Chisholm is set to marry her longterm boyfriend Thomas Starr.

According to Britain’s Daily Mirror newspaper, the parents-to-be got engaged last month.

The couple is reportedly planning to exchange nuptials shortly after the baby arrives.

The pop star and her partner of six years are expecting a baby together in the new year, thought to be around March  2009.

Mel C will be the last of the Spice Girls to become a mother - Melanie Brown has two daughters; Posh Spice Victoria Beckham has three sons with soccer ace David Beckham, and Geri Halliwell and Emma Bunton each have one child.
