Mark Cavendish's missus has stripped down to nothing but a pair of stockings and heels in her sexiest pics ever.
In one snap the glamour model can be seen exposing her tiny frame in sexy pigtails.
In another, she shows off her pert behind in a fishnet skirt – Kim Kardashian eat your heart out.
The sports loving star can often be spotted cheering on Mark from the sidelines of his numerous competitions – no doubt distracting the other racers with her killer looks as she does.
Just a few weeks ago she was spotted supporting her fella during the Tour De France.
Judging by her latest pics, Peta can cheer us on any day.
