3. Dame Helen Mirren, Richard Hammond Christian Slater, The Hives.

There's a 'Hair Off' this week: Richard Hammond - the indestructible one from Top Gear, brings his new, flowing locks to compete with Jonathan's luscious mane. Dame Helen Mirren's naturally girly hair might not be enough to secure victory, but Christian Slater is in with a chance. If it's decided by facial hair, Dr. Matt Destruction from The Hives will walk it, even though he's bald. Bring it on!
