He is a father of four whose next important birthday will be the big four-0. She is barely out of her teens.

But Jude Law and Lily Cole must have found some common ground.

The pair have been spotted in public together on several occasions recently.

Afternoon: Lily leaving Jude's flat after he made an early departure to catch a flight to LA

First they attended a Radiohead concert in Victoria Park, Hackney, East London.

Then Law, 35, took the flame-haired model, 20, for a meal in Covent Garden, followed by a trip to the theatre.

They obviously hadn't run out of things to talk about, for she went home with him, and did not emerge from his Maida Vale flat until the next afternoon.

Bare-legged and dishevelled, she walked to her car parked nearby and drove home. Law had emerged earlier in the morning to catch a flight to Los Angeles for a wedding.

Miss Cole, the face of M&S and Accessorize, is due to start at Cambridge in October. She has had a low-key lovelife until now.

Law's relationships, on the other hand, have been well documented. He divorced Sadie Frost in 2003, and his engagement to Sienna Miller ended in 2006 after he cheated on her with his children's nanny.

Most recently he was seen romancing Rod Stewart's model daughter Kimberly, 28.

A spokesman for Law refused to comment.
