Her boyfriend-of-three years Matthew Rutler popped the question yesterday (14 February) and singer Christina shared her answer with the world.
In a picturesque photo of the pair holding hands in a tropical location, a large sparkling diamond ring is unmistakable on Christina's wedding finger.
Alongside the snap, she wrote: "He asked and I said..."
The 'Beautiful' singer and actress didn't even need to write the answer, which was clearly a YES!
Former The Voice US coach Christina and film producer Matthew met on the set of 2010 movie Burlesque, and they currently live together in Los Angeles.
She was previously married to Jordan Bratman, with whom she has a six-year-old son Max. Coincidentally, their divorce was finalised on Valentine's Day 2011.
Congratulations to the happy couple!
