Harrison Ford and Calista Flockhart are engaged.

The 'Indiana Jones' actor reportedly proposed to the 'Ally McBeal' star on Valentine's Day while the pair were holidaying with Flockhart's adopted son Liam.

The couple — who started dating after meeting at the Golden Globe awards in 2002 — are yet to set a wedding date.

Last year, it was reported Ford (66) and Flockhart (44) had discussed plans to marry and were keen to have a low-key ceremony attended by close friends and family.

Despite initially being reluctant to tie the knot again, twice-divorced Ford — who has four children from his previous marriages — was said to be ready to commit to Flockhart in order to give Liam more security.

A source said at the time: "Harrison wants to give Liam his name. He adores him as though he were his own flesh and blood. Harrison is the only dad Liam has ever known.

"There is just one detail Harrison will have to take care of — marrying Calista. She says it is fine if Harrison adopts her boy, but she wants to walk down the aisle first."

Ford has previously praised Flockhart's parenting skills, saying: "She's the best mom in the world. She's a mother by choice. She adopted Liam before we met, as a single parent which is an awesome responsibility to take. She's devoted herself to Liam and has done a really wonderful job raising him. I'm happy to now have a part of the job."
