Mia Farrow joked this week that she "forgave" Michael Caine for introducing her to ex Woody Allen while wishing the "Dirty Rotten Scoundrels" actor a happy 90th birthday. 

"Happy 90th Birthday to Michael Caine, such a funny and wise friend over many years," the "Rosemary’s Baby" actress, 78, wrote on Instagram on Tuesday. 

She added that when she was married to Frank Sinatra, the crooner’s daughter Nancy dated Caine.  

"If they had married he would have been my son in law! He once played my husband. Just such a lovely man," she wrote, adding, "Actually Michael introduced me to Woody for which i forgave him :)."

Farrow was in a relationship with Allen in the 1980s and had three children – biological son Ronan Farrow and Moses and Dylan Farrow, who were adopted by the couple. 

Dylan has accused Allen of molesting her as a child, which he denies, and the "Annie Hall" star and director later married Mia’s daughter Soon-Yi Previn, who Mia adopted with former husband André Previn. 

Mia and Caine played husband and wife in 1987’s "Hannah and Her Sisters," for which Caine earned his first Oscar.

In 2018, Caine told the Guardian, "I can’t come to terms with" Dylan Farrow’s allegations against Allen "because I loved Woody and had a wonderful time with him. I even introduced him to Mia. I don’t regret working with him, which I did in complete innocence; but I wouldn’t work with him again, no."

Caine told the Daily Telegraph in 2010, "I’m quite a rabid right-winger about pedophilia. If you want to bring back hanging for them then I’m your man. I’ll pull the lever. Don’t get me started on that. I hate it. Hate it."
