WWE: We WILL Protect Our Diva

The WWE is taking some serious security measures to keep WWE diva Maryse Ouellet — one of its most beautiful starlets — SAFE after she received some DISTURBING emails from an obsessed fan.

Sources directly involved with the situation tell TMZ … WWE officials have added additional security personnel at recent events — and plan to keep the extra protection in place as long as the organization feels there is a legitimate threat.

We’re told the organization has also taken additional security measures — but the WWE is being tight-lipped about the security plan in order to make sure the measures are effective.

As TMZ first reported, Maryse filed a request for a permanent restraining order against 61-year-old Lee Silber last week, claiming he’s been sending her creepy letters — and has sworn to “take [her] to heaven with him.”

We’re told WWE staff knows about the situation with Silber — and are on the lookout in case he attempts to attend an event.
