Disguised in a pair of sunglasses, French Open champion Maria Sharapova managed to travel virtually unnoticed on London Underground yesterday.
The French Open champion spent the day at Queen's Club watching Britain's James Ward slip to a straight-sets second-round defeat to her boyfriend, Grigor Dimitrov.
Maria's fellow commuters seemed to be completely unaware that they were sharing a train carriage with a Russian tennis star. Earlier in the day the world number five was watching the tennis in south London alongside Pippa Middleton.
