New York, Jan 28 : Sting and wife Trudie Styler take the cake when it comes to keeping the spark alive.

The duo popped into Meatpacking District hot spot Avenue twice this week and spent both nights dancing and kissing.

"They were both very friendly to staff and to everyone else in the club," the New York Post quoted a spy as saying.

"They were drinking vodka and tonic and seemed very much into each other,” added the source.

Also hanging with the happily married pair was violinist Joshua Bell.

The couple has earlier claimed to enjoy epic bouts of tantric sex. (ANI)
