Friday: Counting The Animals

Every year at this time London Zoo complete their annual stocktake. So how do they count the ants? And are there any elephants missing?

Jamie spoke to David who looks after the counting board... He told us he counts the big animals first and that the fish and invertebrates are a bit more challenging! Have any tigers escaped though? Find out below!

Emma Bunton starts her new job on Monday as co-presenter of Heart Breakfast with Jamie! Make sure you tune in to find out how she gets on and if she remembers to bring her dinner money.

Also make sure you're listening at 7am as we give you your first chance to hear our three Who's On Heart secret celebrities. If you can identify all three of them you can bag yourself a whopping £125,000!

Have a great weekend!
