Aguilera tweeted the news of her engagement. She wrote "He asked and I said." before attaching a photograph of the two holding hands and Aguilera wearing a large diamond ring. A source, speaking to People, said the couple are "very much in love and are really excited to take this next step!" 

Rutler is a production assistant and musician. The couple have been together since 2010 when they met on the set of the film Burlesque, in which Aguilera was starring and Rutler was working as a production assistant. At the time Aguilera was in divorce proceedings from her then husband Jordan Bratman. Aguilera and Bratman married in 2005 and have a child together, 6-year-old Max.

Despite her new relationship and future marriage, Aguilera knows her priorities are to her son. Following the news of her divorce in 2010, as Us Weekly reports, Aguilera told Ellen DeGeneres "He's [Max] the love of my life and I adore him. He's such a character, and he's so happy and at the end of the day, that's what's most important."

The couple currently reside in Los Angeles in Aguilera's $10 million mansion on the Mulholland Estates which Aguilera bought last year. 

Congratulations to the happy couple on their engagement!
