Do you remember those "Nobody Wants To Be Lonely" moments from Ricky Martin and Christina Aguilera? Well, apparently we will continue to see more of these stars together now that the Puerto Rican super star added the duet to his Vegas residency.

Martin launched his new show "All In" at the Park Theater inside the Monte Carlo resort on Wednesday April 5, and impressed everybody when Xtina appeared virtually to join Martin in a duet you could not forget. Both sing the melancholic song on a new renovated twist you can only enjoy during the concert.

The latin sensation flew over all of his biggest hits throughout his decades-long career, including “Shake your Bon Bon,” “La Bomba” and  “Livin’ La Vida Loca” giving his fans a completely deserved concert awaited for his fans who cheered up with him all night long.

Everybody was expecting to see Maluma on the show to sing the hit “Vente Pa’ Ca” along Ricky but it didn’t happen. We reamin hopeful to see this duet in Vegas "All In" concert pretty soon.  

During “She Bangs,” Martin’s super-impressive dancers bring up an unsuspecting fan to dance with them. Many of the moves are similar to those from his music video just like from the TRL-days, as exposed by People.

“Vegas is home now,” he said at the end of his show as the crowd stood on its feet, “so we’re gonna have a really good time,” the artist said at the end of the show.

For now, enjoy Xtina joining Ricky like this:
