Attendees at Jay-Z's New York City stop on his "American Gangster Live" tour got more than what was advertised when he brought out Lil' Wayne, Jadakiss and Diddy during the show at Hammerstein Ballroom last night.

The concert marked the first time the two have shared a stage since speculation spread that they were feuding. Weezy allegedly went at Jigga on last year's "Show Me What You Got" freestyle, while Jay's verse on T.I.'s "Watch What You Say" was rumored to be subliminally targeting Wayne.

Later during the show, Hov hinted that Jadakiss was officially signed to Def Jam by bringing him onstage during "Roc Boys."

"Ya'll already know Memph, ya'll already know Beans, ya'll already know Free," Jay told the roaring crowd. "But what ya'll don't know...Ruff Ryder, Roc-A-Fella, Roc Boys, Jadakiss is in the building."

Jay also brought out Diddy for 50 Cent's "I Get Money" remix while Memphis Bleek, Beanie Sigel, Freeway and Young Gunz also made appearances. They performed during a
Roc-A-Fella block that included "Roc The Mic," "What We Do," "Can't Stop Won't Stop" and "Ignorant Sh-t."

Jay also took time to acknowledge the death of Donda West, Kanye's mother, with a moment of silence. “I want to dedicate tonight's show to Kanye West," Jay announced. "There's a death in the family. We love you, Kanye."

Aside from  new joints from American Gangster - "Pray," "Party Life" and "Blue Magic,"  -Jay ran through classics like "Where I'm From," "You Don't Know," "I Just Wanna Love You,"  "Jigga My N-gga" and "Big Pimpin'."

Atlantic Records executives Lyor Cohen and Kevin Liles, marketing and music executive Steve Stoute, the Roots’ ?uestlove and New Jersey Nets forward Richard Jefferson were all in attendance.
