At the time the singer took to her official Twitter page tweeting, “He asked and I said…”
The message was accompanied by an image of the couple’s hands embraced and Aguilera diamond sparkler on full display.
“They’re very much in love and are really excited to take this next step!” a source close tells PEOPLE magazine.
Aguilera, who was previously married to music manager Jordan Bratman, already has six year old son, Max.
This will be the first child for Rutler.
The singer and film producer met on the set of “Burlesque” in 2010.
Congrats to the happy couple.
