R&B singer John Legend has laughed off reports he is having a secret fling with U.S. TV presenter Maria Menounos - insisting he only has eyes for longtime beau Christine Teigen.

The Ordinary People hitmaker was rumored to be embroiled in a steamy affair with the Entertainment Tonight star, after the pair was spotted enjoying a seemingly romantic rendezvous earlier this year.

But Legend has quashed the speculation, insisting he is simply pals with the Greek beauty and remains blissfully happy with model girlfriend Teigen.

He tells the New York Post’s gossip column Page Six, "I am still happily dating my girlfriend, Christine Teigen, and have been for about a year now.

Maria Menounos is just an acquaintance and we were having a friendly drink."
