There is no good way to find out that your significant other is cheating on you, but one woman in Russia discovered her boyfriend's infidelity in a pretty surprising manner. Marina Voinova was looking up an address on Russia's version of Google Maps, Yandex Maps. She wanted to get a closer glimpse of a building using the street view feature. So she zoomed in, and there was her boyfriend Sasha with his arms around another woman.

Well, perhaps it was just an old picture that was taken before he and Marina were a couple. Only problem with that was that Marina and Sasha had been together for five years, and the Yandex Maps feature has only been around for three years. And, the plot thickens: Sasha is seen in the photograph with his arm in a cast, which he had to wear last summer.

When Sasha returned home, Marina asked him to type the address she had looked up into Yandex Maps. Once Sasha saw the incriminating image of himself, Marina said, his entire face changed color and he confessed everything.

Marina promptly broke up with her boyfriend after her discovery and said it would be "silly to blame the Web for my boyfriend's unfaithfulness." Now, instead of searching online maps, Marina is single and searching online dating sites.
