The Australian star thinks her two-year-old son Ethan is a linguistic genius and she is teaching him Spanish, Chinese and Italian before he has even fully mastered the English language. Speaking on British chat show `Lorraine`, Dannii enthused: "He is talking a lot. He`s very good with languages so my friends who speak different languages are speaking to him. From TV shows he`s learning different languages - there`s one with a bit of Spanish in, another one with Chinese in it so he`s like, `Ni Hao`! And when my Italian friend speaks to him he says, `Ciao!`. He`s brilliant." The 41-year-old Project D designer also admitted she doesn`t go to the gym much these days because being a single mother gives her all the exercise she needs. Dannii - the sister of pop megastar Kylie Minogue - also revealed her top health tip is drinking a special type of milk. She said: "I don`t do any fitness. Because I don`t train or work out, I`m just lifting the baby, that`s my weights workout. I do watch what I eat. I discovered this milk in Australia called a2, it`s been a huge success there and it`s coming over here. "It`s not GM modified. They`re just special cows. I actually think they`re in a field with a red rope around them and sunglasses! Possibly like Jesus."
