Katie Ritchie who plays Sally Fletcher, and Emily Symons (Marilyn) have been friends since 1989 after meeting on the set of Home and Away.
And to celebrate Emily Symons' recent baby announcement, Katie posted this old-school snap of the pair from 1992 to her Instagram account.
“Babies are precious and so are old friends,” she captioned.
And they havn't aged a day!
Both Kate and Emily have been prominent figures in Summer Bay over the years, with Emily adopting the role of Marilyn from 1989 to 1992, and again from 1995 to 1999.
She then moved to London and appeared on British soap Emmerdale before returning in 2010 to reprise her role as Marilyn.
Meanwhile, Kate played the famous Sally Fletcher from 1988-2008, returning for an eight week stint in 2013 to celebrate the show's 25th anniversary.
Emily is due to be a mother for the first time in August – a year after Kate gave birth to her daughter Mae.
A statement on her publicist's website revealed that the actress is due around her 46th birthday and will take a break from filming before reprising her role as Marilyn.
Emily and her partner went through a couple of rounds of IVF before conceiving.
Best of friends, both on-set and off-set.
Congratulations Emily!
