The 57-year-old actor - who was nominated but failed to win Best Actor for his performance in 'The Wrestler' at last year's Academy Awards - is besotted with Russian model Anastassija Makarenko and insists their six-month romance has brought him more happiness than career success ever could.
He said: "She's a gift from heaven. Obviously she's a very beautiful woman. But she's got the biggest heart, she's got a great family, she's really close to her mother and father - they're great people.
"I wouldn't trade her in for 20 Academy Awards."
Anastassija has already taken the actor - who recently presented her with a Pomeranian dog named Tango - to Germany to meet her parents and says they have given the romance their blessing.
She told People.com: "They loved him. He's the most beautiful man in the world, he's a sweetheart, and the best boyfriend."
It was recently claimed that Mickey - who has been married twice before - and Anastassija are planning to wed in April.
A source said: "They haven't booked a venue or made any solid plans. He just knows he wants to do it in April, and he's been asking what is involved in a traditional Russian wedding ceremony."
However, the couple refused to comment on the rumours.
