Prince kicked off the first show of his planned residency-style “Welcome 2 America” tour, which he’s calling his “21-Night Stand,” at Los Angeles’ Forum on Thursday, and there was a host of celebrities in attendance.

Among the crowd? Eva Longoria and her date, Eduardo Cruzwere.

The couple probably would have gone unnoticed, had Prince not invited Eva to join him on stage. With all eyes upon her, the Desperate Housewife showed the audience that she knows how to dance, unlike Kim Kardashian. Burn!

After Eva made her way back to her seat, RumorFix.com spotted her and Eduardo Cruz kissing and cuddling by the stage.

Woman scorned. She’s flashing nipples on David Letterman, and now making out behind the bleachers.
