Actor Clint Eastwood's daughter Alison is engaged.

Fashion designer and actress Alison Eastwood, 40, is set to wed her Chainsaw Gang co-star Stacy Poitras after five years of dating.

Poitras reveals he even asked the Dirty Harry star for his daughter's hand in marriage, telling Celebuzz.com, "Clint is a cool guy... but he's definitely a man of few words. I quietly asked him when we were alone if it would be all right if I asked for his daughter's hand in marriage.

"He coolly looked me in the eye and softly said, 'You better take that up with her,' to which I replied, 'So, I have your permission?' And he said, 'Yes...' I'm the luckiest guy in the world."

Alison's mum is Maggie Johnson, who was married to 82 year old movie icon Eastwood from 1953 to 1984.

The wedding news comes just three days after the actor/director's daughter with Francis Fisher, Francesca, was named Miss Golden Globe 2013.
