Wayne Rooney�s younger brother is keeping it in the family � he�s dating Coleen McLoughlin�s cousin.

Graham, 18, escorted 17-year-old Carly Gardiner to Coleen�s glitzy 21st birthday bash this weelend, but the pair have apparently been an item for a year after being introduced by Wayne.

How have we not found out about this earlier?!

However, Graham � a dead ringer for Wayne � has decided not to follow in his famous brother�s footsteps in at least one way.

He�s given up a promising football apprenticeship with Wayne�s first club Everton to pursue a boxing career instead.
