Christina Aguilera has plenty to celebrate this month!

Less than a week after announcing her engagement to longtime boyfriend Matt Rutler, Us Weekly reports that the singer is expecting her second child.

Aguilera, 33, already has a 6-year-old son, Max, with her ex-husband, Jordan Bratman. They split in 2010 after five years of marriage, and Aguilera soon after began dating Rutler, whom she met on the set of her movie, Burlesque. This would be the first child for Rutler.

It is unclear how Aguilera's pregnancy might affect her future on The Voice. She is taking a break for Season 6, which premieres Monday at 8/7c on NBC, and fellow coach CeeLo Green announced on Wednesday that he would not be returning to the singing competition.
