Christina Aguilera is engaged to wed Matt Rutler.

The 33-year-old singer started dating the production assistant after they met on the set of her 2010 film Burlesque.

And Christina announced to her Twitter fans on Friday she and her longtime beau are now ready to take a walk down the aisle.

'He asked and I said..,' she wrote in a coy message to her 11.6 million Twitter followers, which was attached to an image of her sporting a huge engagement ring while holding hands with Matt above a beautiful beach setting.

Apparently the couple are overjoyed to be finally tying the knot.

"They're very much in love and are really excited to take this next step!" a source told People magazine.

Christina has spoken previously about how perfect Matt is for her.

The songstress is simply filled with joy when she's around him, and she finds his eccentricities refreshing.

"He's the love of my life, and I adore him," Christina gushed on The Ellen DeGeneres Show back in November 2010, around the time she separated from her first husband. "He's such a character, and he's so happy and at the end of the day, that's what's most important."

Christina's divorce from ex-husband Jordan Bratman was finalised in April 2011, six years after their 2005 wedding. Around the time she officially separated from Jordan in late 2010, the singer began dating Matt.

Christina shares six-year-old son Max Bratman with Jordan.
