Mila Kunis and Ashton Kutcher are allegedly very close to getting engaged, according to multiple sources close to the couple.

Sources via Us Weekly have allegedly that Kunis and Kutcher are ready to settle down and get married.

"They talk about getting married and having kids," one source said as of Christmas Day. "An engagement is imminent."

Another friend of the couple said that Kunis and Kutcher are "inseparable." The couple allegedly "hangs in [Kutcher's] trailer" while he's on the set of his CBS sitcom Two and A Half Men.

Kunis and Kutcher met in 1998 on the set of That '70s Show, which lasted for eight seasons and concluded in 2006. During that time, Kunis and Kutcher were just friends and co-workers, going their separate ways after the sitcom ended.

Kunis dated child actor Macaulay Culkin in 2002, with their relationship lasting until the pair split in 2011. Meanwhile, Kutcher was in a high-profile marriage with actress Demi Moore, a relationship that also ended in 2011.
