Brad Pitt wears David Beckham's underwear.

The 'World War Z' actor's fiancee Angelina Jolie is a huge fan of the footballer's brand for H&M and recently stocked up on Brad's behalf.

A source told The Sun newspaper: ''Ange has been a regular at her local branch of the clothes chain since she moved to Surrey in England.

''Last week the store closed so she could have the shop to herself. She bought loads of stuff, including some of David's pants.''

It was recently revealed that the superstar couple - who raise six children together, Maddox, 11, Pax, nine, Zahara, seven, Shiloh, six, and four-year-old twins Knox and Vivienne - have given each other affectionate nicknames, with Angelina referring to Brad as ''Kitty'' and Brad calling his fiancee ''Miffy''.

A source said: ''Brad and Angelina are very lovey-dovey towards each other and don't care who sees it.''

The couple also use their nicknames to book into hotels so people don't know who's really staying there.

Before meeting Brad, Angelina used to check into hotels and make restaurant reservations using the alias ''Shiloh Baptist''.

The pair then continued to use the fake moniker while they were dating, but decided to change their secret names after their first biological daughter, Shiloh, was born in May 2006.

Angelina said: ''It's a name I always liked. I used to go under it in hotels: Shiloh Baptist. I'd gone under it when Brad used to call hotel rooms I was staying in.''
