Madonna rounded off her Sticky and Sweet tour in Tel Aviv, Israel last night by inviting some of her brood to join her on stage. What better way to mark the end of the most successful tour ever by a solo artist than getting the kids to come on and do their bit? Lourdes, who turns 13 next month, shows off her piano skills and joins in the tightly-choreographed finale, while nine year-old Rocco does a freestyle routine and has it large in the DJ booth. How long before Lourdes lands a record deal of her own? Watch both clips of the famous kids in action and tell us what you think.
