The Congo international has been linked with a switch to White Hart Lane as Spurs boss Harry Redknapp bids to sign a new defender.
But Allardyce was quick to rubbish reports that Spurs were in for the 25-year-old.
"It is an absolute nonsense," Allardyce told Sky Sports News.
"As far as I'm concerned, there has been no contact with Tottenham - and I know that as I spoke to Harry Redknapp."
Meanwhile, Allardyce has tipped new loan signing Franco Di Santo to shine this season.
"He is a young man that is frustrated at not playing too much first-team football last season," Allardyce said of the Chelsea youngster, who will spend the whole campaign at Ewood Park.
"He is looking forward to playing here - he is a talented player, if not a little inexperienced, with lots of ability and I think there is a lot to come from him, but I think we will take it easy with him.
"He will play a lot of games, but I don't think he will play every game but when he gets used to it I think he will be a force for us."
