Christina Aguilera took to Twitter to announce a special event in her life - her engagement to boyfriend Matthew Ruttler whom she's been dating for three years that took place over the Valentine Holiday.

People reports that the proposal has been brewing for a long time and Rutler has been working hard on designing the ring. Each stone carries a special meaning in their relationship.

"Matt spent over a year designing the ring with the ring designer to represent their three-year journey together as a couple," the source says. "He has been planning this for a while and was just waiting for the right time - the ring has been done for months. Every single placement of each stone has a reason and meaning."

An insider for People cites the band's weave as symbolizing the crossing of their paths with the narrows base which "reflect how their bond continues to grow closer and stronger over time."

"There are nine special multi-color gemstones that you cannot see. They all symbolize something meaningful to the couple. Christina is very spiritual and having the stones touch her actual skin will emit positive energies surrounding her at all times. They represent things like love, protection and healing," says the insider.

The vintage setting was inspired by some of Christina's favorite pieces. Rutler reportedly "took two of Christina's favorite rings ... to design something that incorporated [both designs] into one," the source says. "Similar to both their lives coming together as one."

A source of People says that the couple is "very much in love and are really excited to take this next step." Friends of the singer and The Voice judge say the songbird cannot wait to have another child and suggest that the couple are well on their way to trying to have a baby together.

33-year old Christina met Matt on the set of 'Burlesque' where he was a film assistant and the movie-lead was in a turbulent time having just gone through a painful split from her first husband Jordan Bratman, which was finalized three years ago, says CTV News.

Christina has a six-year-old Max with her ex-husband, who they share custody of.
