According to the actor’s Twitter page, Greg Vaughan is doing well after leaving the role of Lucky on GH.

He most recently tweeted: “I’m officially making my return to the NEW 90210 tomorrow!! I’m 100% thankful for all your love & support! God Bless You All!!! HAHAHA”

For those of you who don’t know, Greg played fireman Cliff, who rescued Donna from a wildfire and then dated her for a little bit, on the original “90210” in 1997.

He also tweeted about a movie he is currently filming called “Sebastian.” The film is about a woman dying of cancer who is cured by a young stranger who claims to be the soul of her aborted child. Greg plays a doctor in the film that is chock full of soap stars including Kiko Ellsworth (ex-Stan, GH; ex-Jamal, “Port Charles”) and Brain Gaskill (ex-Rafe, “PC”).

If you’d like to meet Greg in person, he noted that he will be at Zanies Comedy Night Club at 230 Hawthorn Village Commons, Vernon Hills, IL on November 21 at 1:00 PM. For more information check out the Zanies website.
