Jewish actress Mila Kunis and boyfriend Ashton Kutcher are engaged to be married, according to US Weekly and the E! entertainment news website.
The longtime friends, who have been dating for about two years, appeared together on the popular television sitcom "That '70s Show." Their characters - Jackie and Kelso - dated on the show.
Photographs on the US Weekly and E! websites taken of Kunis on Thursday in Los Angeles show her sporting a large diamond ring on her left hand.
The Ukrainian-born Kunis moved to the United States as a child. She has spoken in the past about wanting her future children with Ashton to be raised Jewish.
Kutcher, 36, finalized his divorce from actress Demi Moore in 2013. While he is not Jewish, he is known to be a devoted student of Kabbalah, which he took an interest in while married to Moore.
The two attended the funeral of Kabbalah Chief Rabbi Philip Berg in Safed in northern Israel in 2013.
Representatives for Kunis and Kutcher did not immediately respond to requests for comment.
