Dr Emily Andrea has posted an adorable picture of her son Theo as she celebrates his fifth birthday on Monday 22 November, and it already seems he's taking after his dad Peter Andre.The little boy was dressed in a fabulous military-style costume and held a microphone as it appeared he was ready to perform, following in the Mysterious Girl singer's footsteps. Wearing a matching hat and velvet trousers, the little boy posed on the hood of his mini toy sports car.
