‘Rock’ reunion

TRACY Morgan — who triumphantly returned to host “SNL” after being severely injured in a car wreck last year — celebrated after the show at Heartland Brewery on West 43rd Street with his wife,

Megan Wollover, and his former “30 Rock” castmates Tina Fey, Jane Krakowski and Jack McBrayer, spies told Page Six. Also at the bash were Larry David, MaryKate Olsen, Lorne Michaels and various “SNL” players as well as the night’s musical guest, Demi Lovato, with Gigi Hadid and Joe and Nick Jonas. “Tracy made the rounds and got hugs and tons of support,” said a spy at the party. “It really was like a homecoming.”
