What a bum deal: Robert Pattinson is pants inspiration

Robert Pattinson has apparently inspired a rage of underwear at Marks & Spenser.

The 24-year-old Twilight actor has been named as the inspiration behind Marks and Spencer’s new slim-fit underwear.

The hilariously dubbed R-Pants are designed to be worn under skinny jeans.

One in four men reportedly still buy their pants from M&S – including Rob who was papped picking up pants there not long ago.
