The 'Beautiful' singer showed off her blossoming baby bump to full effect on Saturday (10 May) while performing at the KIIS FM Wango Tango concert in Los Angeles.
Christina highlighted her fab figure in a tight-fitting LBD, teamed with seriously high skyscraper heels.
The blonde songstress is expecting her first child with fiancé Matt Rutler. Christina met the film producer on the set of her 2010 movie Burlesque, with romance – and an engagement – coming later.
News of her pregnancy surfaced in February – just a week after the engagement confirmation - but she has remained generally coy about her baby joy.
However, it was reported in March that Christina confirmed her pregnancy while performing in Malaysia and revealed it will be a baby girl.
She made her first reference to the pregnancy the following month in April, tweeting a picture of herself and Matt alongside the caption: "Baby loves NYC." In the picture, Matt can be seen with a protective hand on Christina's stomach.
Christina, 33, is already mum to son Max, six, from her marriage to record exec Jordan Bratman.
