Rolling Stones frontman SIR Mick Jagger has denied adopting a fertility boosting diet in a bid to father a child with his girlfriend L'Wren Scott. The singer - who already has seven children - was reported to have changed his eating habits to include foods that would potentially increase the couple's chances of conceiving. Pregnancy advice website reported Jagger has been eating plenty of avocados and drinking a glass of goji berry juice every day to improve his fertility. However, a representative for the 64-year-old has hit back at the story, insisting the rumours are "cobblers" (nonsense).
