Cristiano Ronaldo's model girlfriend troubled by stalker

Cristiano Ronaldo's model girlfriend, Shayk, has filed two police reports against an alleged stalker, who repeatedly appeared at her building and even entered into her apartment.

Police sources have confirmed the footballer's girlfriend has filed several complaints about an unidentified perpetrator who has been sending her flowers, gifts and other items, and has showed up at her address repeatedly over two years.

The man, who has been caught on building's security videotape, scarily managed to get into the beauty's apartment while it was being renovated after flooding caused by Superstorm Sandy months ago.

When Shayk returned, she found the intruder in the apartment but managed to run out and call 911.

The man had left by the time cops arrived.

Shayk filed a complaint, but no arrests were made.

A source told the publication that the stalker again returned on Sunday, but could not reach the apartment, and the model was alerted by the building staff.

She has reportedly filed yet another complaint, and is now asking for a restraining order.
