Christina Aguilera, who gave birth to a baby girl on Saturday (Aug. 16), has officially released her daughter's name, Summer Rain Rutler!

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.

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.

Christina Aguilera got the most romantic Valentine's Day present. Her boyfriend, film producer Matt Rutler, proposed and Xtina accepted. She was quick to show off the ring, too.
