The Saturdays singer - who is expecting her first child, a daughter, with her fiance, England rugby player Ben Foden - admitted while she is "proud" of her pregnancy, her tot will be born by the time the video is out so she doesn't think it would "make sense" for it to feature in the shots.
Writing on her twitter page, Una said: "Up and ready for to shoot our new video. Bump will be edited out of the video so our director will be working his camera skills magic today!
"I don't want bump in the video because she will be born when it hits the tv screens so it wouldn't make sense or relevance by then!

"And I am proud of my bump but ill be even more proud of her when she is out, its not like she's going to be in utero forever! (sic)"
However, Una's bump worries were quickly put to the side when she arrived at the shoot and was "showered with amazing baby gifts" from her The Saturdays bandmate Frankie Sandford.
She tweeted: "Aw just arrived at the shoot and got literally showered with amazing baby gifts from @FrankieTheSats she has great taste in baby things!! (sic)"
