Christina Aguilera

While many soaked up the sun, Christina Aguilera celebrated the first day of summer (June 21) by showing off her growing belly on Twitter!

A pregnant Christina Aguilera took the stage yesterday at the Wango Tango concert in Los Angeles where she performed 'Say Something' with the band A Great Big World.

After yesterday's announcement that Gwen Stefani will be replacing Christina Aguilera on NBC's 'The Voice,' Christina took to Twitter to talk about what she has planned during her time away from the reality competition show.

NBC's 'The Voice' will be welcoming a new face to the judges panel for season seven: Gwen Stefani! Stefani will be sitting and slamming buttons in Christina Aguilera's chair, who is currently pregnant with her second child and will be taking time off to care for the new baby. Season seven is scheduled to begin filming in June and run through the fall 2014 television season.

Finally! Christina Aguilera, pregnant with her second child, which she revealed is a girl, shared a photo while in NYC with her fiance Matthew Rutler. We can finally see her baby bump, as she put it on full display in the pic, something she hadn't done up until now.

Stunning singer Christina Aguilera is expecting her second child and guess what? She's having a baby girl.

A 4-year-old boy is moved to tears by the A Great Big World song 'Say Something,' and it is awww-dorable!

Like her chart-topping sister Lorde, little sis India Yelich-O'Connor seems to want to break into the music business. The 15-year-old recently uploaded a cover of A Great Big World and Christina Aguilera's 'Say Something' to SoundCloud.
