So says the National Enquirer.

Harrison and Calista have spent six years together and are reportedly planning to get married.

Her seven-year-old son, Liam, whom she adopted in 2001, is said to be the catalyst for the upcoming nuptials.

According to the Enquirer, Harrison, 65, who has four grown children of his own from two previous marriages, wants very much to adopt Liam and give him his name.

Calista, 43, who has never been married is said to be insisting on getting married before the adoption can take place.

You can’t blame her for wanting marriage after all this time. The two of them seem to fit like a glove and making it official by getting married will genuinely bond them as a family.

Vows are expected to be exchanged in a private ceremony in California after Harrison completes promotional stints for his latest movie, Indiana Jones and the Kingdom of the Crystal Skull.

The movie is scheduled to be released at the end of May.
