Christina Aguilera performs + flaunts the bump at ‘Wango Tango’...

Pregnant chanteuse Christina Aguilera was the picture of radiance when she took to the stage at yesterday's KIIS FM Wango Tango concert in Carson, California. It was a nice way to ring in Mothers Day and she looked really happy. The only thing she could do with is toning down on the tan because her hands looked a little too tangoed and it was too big a contrast from her face!

For the performance, she joined pop group A Great Big World for their hit single 'Say Something.' The next time Aggy performs on a stage like this, it will be her OWN hit single (hopefully). I can't remember the last time this has actually happened but I look forward to the new album after she gives birth to her daughter this Autumn.
