Christina Aguilera gets engaged to Matt Rutler

Pop star Christina Aguilera and her film producer boyfriend Matthew Rutler have got engaged after almost three years of dating.

The 33-year-old singer announced the news yesterday on Twitter by sharing a snapshot in which she and Rutler can be seen holding hands with a diamond ring shinning bright, reported People magazine.

"He asked and I said...," Aguilera wrote with the picture.

The singer met Rutler on the set of 'Burlesque' in which she starred and he was a film assistant.

At the time Aguilera was going through a painful split from her first husband Jordan Bratman, which was finalised three years ago. They have a son together.
