Riverdale star Luke Perry in hospital
Luke Perry is under observation in hospital, his publicist has confirmed.
It has been reported that the Riverdale and Beverly Hills, 90210 star, 52, has suffered a stroke.
A spokesman for the actor told the Press Association: "Mr Perry is currently under observation at the hospital."
Shannen Doherty, who played his love interest Brenda in Beverly Hills, 90210, appeared to send a message of support to Perry when she shared a picture of them together on the show.
According to TMZ, paramedics responded to his home in Sherman Oaks, California on Wednesday morning and he was transported to a nearby hospital.
Perry is best known for playing Dylan McKay in the teen show Beverly Hills, 90210 and is currently starring as Archie's father Fred Andrews in Riverdale.
The news of his hospitalisation comes a day after it was confirmed the cast of Beverly Hills, 90210 will reunite for a reboot of the 90s hit.
Talk of a return to the much-loved show has been in the pipeline for some time, and on Wednesday Fox announced that it was rebooting the series with original stars Tori Spelling, Jennie Garth, Jason Priestley, Ian Ziering, Gabrielle Carteris and Brian Austin Green on board.
Perry and Doherty are not thought to be attached.
