Jennifer Lopez - Wisin Y Yandel Pull Out Of J.lo/enrique Tour

The Puerto Rican stars insist they had to scrap plans to join one of the summer's biggest tours when they realised they would not be able to put on the quality of show fans have come to expect.

Blaming "unresolvable issues" for their decision, Wisin y Yandel state, "It is with sadness and regret that we have decided to withdraw from the tour. Our sincerest apologies go out to our fans. We wish Jennifer and Enrique, as well the tour, the very best."

And it appears Lopez has already forgiven the pair for dropping out of the trek - she took to Twitter.com on Tuesday (02Jul12) to congratulate her pals on the success of their new album Los Lideres on its first day of release.

She tweeted, "Congrats to my brothers @wisinyyandel for their #1 album!!"
