"They're over the moon in love," a friend of the pair told the magazine.

Ritchie -- who's directed many films including Lock, Stock and Two Smoking Barrels, Snatch., RocknRolla and Sherlock Holmes -- was previously married to Madonna, with whom he has an 12-year-old son, Rocco, and also an adopted son, seven-year-old David Banda.
