Tennis, social networks, and young love.

Cassie Matthews (21) joined the tour at the beginning of grass season to help her brother, the 19th-time major winner Tyler Matthews (31), in his training sessions.

The youngster Nicholas Demidov (21) was caught talking to the American beauty.

They've been seen together multiple times on and off the tennis courts, and there are pictures of them in the social network Picturesque.

Rumor has it that Cassie must go back to school at the end of the summer.

Will they be able to handle the distance and misleading conversations?
