"Thank you for the many wishes on our twins...Peter and I are due to become parents in April. But twins come a month in advance so March it is," Celina wrote on Twitter.
Celina married hotelier Peter Haag in 2011, and she is enjoying her journey to motherhood.
"Twin pregnancies have their risks and unique experiences which singleton birt's don't have. So it's been quite a journey," she added.
It's been a while since Celina was seen on the big screen. So when a fan asked her on Twitter - "Where are you dear? No more movies," she responded: "Maternity break...its difficult to dance n seduce the hero whilst pregnant with twins."
She will next be seen in "Will You Marry Me?".
