WWE Diva -- 3 Years of Protection from Heaven-Obsessed Fan

The man accused of stalking WWE star Maryse Ouellet has been legally banned from going anywhere close to the beauty for the next 3 years ... TMZ has learned.

An L.A. County Superior Court judge granted Maryse's request for a restraining order against 61-year-old Lee Silber this morning -- requiring the guy to stay at least 300 feet away from the Diva ... for the next 3 years.

As we previously reported, Ouellet claims Silber has been harassing her constantly -- leaving more than 50 delusional voicemails on her cell phone ... and sending her increasingly scary letters, promising to track her down in L.A. and "take me to heaven with him."

Several attempts to reach Silber were unsuccessful.

UPDATE: Maryse was accompanied to court by WWE superstar The Miz. On their way out of the courthouse, both WWE stars were pretty tight-lipped, but seemed satisfied with the result.
