Jude Law had to endure taunts about his receding hairline after dropping in on his comic pal yesterday.

The pin-up actor had turned up to see friend Kayvan Novak filming C4 comedy Fonejacker in South London, and got a good old ribbing over his thinning hair for his troubles.

A source tells The Mirror, “People burst out laughing when he took off his cap, and said he needs a hair op. He told them to 'f*** off' but in the end he laughed along."
