After months of rumors and speculation, actors Ashton Kutcher, 36, and Mila Kunis are officially engaged.

An insider confirmed the news to People magazine after Kunis, 30, was spotted rocking a diamond ring on her left ring finger Thursday.

The Friends With Benefits actress coyly showed off her ring while wearing an ivory sweater, black leggings, a grey purse and sunglasses while she was out and about shopping with her mother.

This will be the second marriage for Kutcher who was previously wed to actress Demi Moore. It was revealed in November of last year that their divorce was final after being separated for more than two years.

A source also said in December 2013 that Kutcher and Kunis were unofficially engaged before his divorce was finalized.

"[The engagement] just happened. They were going to make it official after the divorce went through- though they don't really see the need to issue a press statement about it. Ashton and Mila are progressing quickly because [since they were already longtime friends] they skipped over a lot of the step couples usually go through," a source said.

Now, they're ready to have children. Kunis has also expressed her desire to have children over work.

She told Glamour magazine in 2012, "I'd rather be in love and have a ban than a movie."

The source added that the soon-to-be Mrs. Kutcher is already opening up her schedule to spend more time with Kutcher and her family.

The two began dating in April 2012 and are said to have been inseparable since.
