"#90210 Reunion (SPOILER ALERT)..Donna and Steve got married and had a baby!" the actress said in reference to the characters they portrayed on the 1990's drama alongside a selfie of themselves posing with Spelling's 9-month-old son Beau.
"Jk. Just hanging with Uncle @ianziering and #BabyBeau...," she continued before asking fans for input on what they might want to see in a potential 90210 revival.
"But, if there were to be a reunion of sorts... what WOULD you want to see happen?"
The cast of 90210, including Spelling, Luke Perry (Dylan), Jennie Garth (Kelly) and Jason Priestley (Brandon), last reunited in November 2016 to pay tribute to Shannen Doherty (Brenda) who was battling cancer at the time. Doherty announced in April that she is in remission from breast cancer.
Garth in July, mentioned on NBC's Today that she wouldn't be opposed to starring in a potential 90210 revival. "Everybody wants to see that now," she said.
