Rapper Jay Z and his singer-wife Beyonce Knowles deny split rumuors by enjoying a close moment in Portofino, Italy.

They were sported together holding hands and exchanging "sincere warmth" and body language expert Leil Lowndes believes the action shows they are expressing "sincere warmth", reports contactmusic.com.

The couple were seen getting up close and personal throughout a stroll through the Italian fishing village and Lowndes told HollywoodLife that it is "lovely the way (Jay's) hand is (always) draped" over the singer's shoulder.

The couple have been performing on their `On the Run` tour of late, but it has been claimed they could split when their gigs come to an end in Paris.
