The Saturdays singer recently confirmed she and boyfriend Ben Foden are expecting their first child together and she is pleased not to be suffering from too many side effects so far.
She said: "So far my pregnancy has been easy. I`ve not been sick, I`ve just got an amazingly sensitive sense of smell. I can`t bear strong cheeses."
Una and Ben are "excited" about their new arrival but the `Ego` hitmaker is also hoping she and Ben can find the time to get married soon.
She told more! magazine: "Ben and I are just so excited. It`s an incredibly time. And we definitely want to get married soon. Who knows when it will be, but I can`t wait to become Mrs. Foden."
Una`s bandmates are equally excited about the baby and can`t wait to help her out with parenting duties.
Mollie King said: "It was a shock but we`re al; so happy. We`re giving her loads of support. It hasn`t made me broody but we`re all going to be surrogate mums to the baby."
Frankie Sandford added: "It`s not the right time for me either, but we`ve been joking with Una that we`ll have the baby for all the fun stuff but the minute he or she starts crying, we`ll hand it right back."
