Montel Williams-The Salahis Used Me to Promote Their Event

Montel Williams is threatening legal action against no one's favorite couple -- Michaele and Tareq Salahi -- accusing them of using his name to promote an upcoming event.

The Salahis are planning a charitable event next month to celebrate the reopening of their Oasis Winery in Virginia -- and, apparently, they've listed Montel as one of their celebrity guests.

That's news to Montel -- because his rep tells TMZ, "Montel doesn't support the Salahis, doesn't know them and did not give them permission to use his name." He says the event organizers also, falsely, announced that Montel's MS Foundation is involved

The rep says a cease and desist letter was fired off to the Salahis today -- demanding they stop using Montel's name and foundation -- and we're told both have since been removed from the website promoting the event.
