They were one of the biggest girl-groups of their era.

And now 33-year-old Amelle Berrabah has announced that she's pregnant with her first baba... which means there is another gorgeous little Sugababy en route. https://twitter.com/Amelle_B_SRosa/status/945409454350176257 The 33-year-old singer told her Twitter followers on Christmas Day that she was "eating for two". Sharing a snap of a plate packed with roasted parsnips and all the trimmings, Amelle wrote: "Hope everyone had a great Christmas! Ate so much but then again, I'm eating for 2... so I get a pass!" https://twitter.com/Amelle_B_SRosa/status/945754892278386690 Then on Stephen's Day she was back in the gym - doing a "very light workout and stretch". "Mumma's hungry!" she added. Answering questions from fans, Amelle says she's around three months pregnant - and so she doesn't know whether she's having a boy or girl yet. She's been married to Marcio Sousa Rosa, a record label executive, since 2014; they eloped to Mauritius and wed on the beach just a month after their engagement. Original Sugababes member, Siobhan Doherty, gave birth to her first child - a son - in August. And Heidi Range, who joined the band in 2001, is also currently expecting her first child. The Sugababes launched in 1998, released a debut album in 2000, and had several different incarnations before splitting up for good in 2011. They had six No.1 singles and five top 10 albums in their native UK.
