PERRY DRUG PROBE CASTS DARK CLOUD OVER FRIENDS' 30TH ANNIVERSARY

Cast doesn't know how to celebrate without Matthew

MATTHEW PERRY’s grieving Friends co-stars are determined to keep his legacy alive when celebrating the classic show’s 30th anniversary this year, but sources say the current criminal probe into his death has cast a dark shroud over their plans.

Sources snitch the surviving cast members — Jennifer Aniston, 55, Lisa Kudrow, 60, Courteney Cox, 60, David Schwimmer, 57, and Matt LeBlanc, 56 — are struggling to figure out how to mark the hit show’s anniversary without the sordid details of Matthew’s last days and death overshadowing the celebration.

As GLOBE reported, the TV funnyman was found dead in a hot tub at his Pacific Palisades home on Oct. 28 last year, due to the powerful anesthetic ketamine, called Special K by druggies.
