The Real Housewives of Orange County is getting another blast from the past with the return of original cast member Jo De La Rosa. 

The 43-year-old is making her long-awaited return to the franchise after 15 years.

While she won't be featured as an official cast member, the influencer filmed the season 18 finale party with Tamra Judge, Heather Dubrow, Alexis Bellino and more. 

Tamra, 56, replaced Jo on the Bravo show in 2007, but the pair now appear to be firm friends. 

After filming the finale, Tamra took to X (formerly Twitter) to share a selfie with the brunette, captioning it, 'Jo's back in the mix.'

Jo, now 43, was part of the original cast when the show premiered on Bravo in 2006

She also shared a video of Jo and Alexis, who is also making her return to the franchise, as they celebrated wrapping filming.

'That's a wrap!' shrieked Tamra as Jo and Alexis cheered, before jokingly adding, 'Nope, cameras aren't down!'

Jo appeared as a full time cast member on the first two seasons of RHOC, which aired in 2006 and 2007.

She briefly appeared as a guest on seasons three and four, before fading from the spotlight.

Along with her ex-fiancee Slade Smiley, she starred on the 2008 spin-off Date My Ex: Jo & Slade for one season. 

That same year, Jo released her debut album, Unscripted, which failed to set the charts alight. 

Meanwhile, the 18th season of The Real Housewives of Orange County is set to air on Bravo this year.

Tamra, Heather Dubrow, Shannon Beador, Gina Kirschenheiter, Emily Simpson and Jennifer Pedranti are all returning in a full time capacity.

Former star Alexis Bellino, who exited the show a decade ago, is also back in a supporting role. 

Newcomer Katie Ginella has also filmed this season, although it's still unclear if she'll be an official Housewife or not. 

Tamra recently called the show's new season 'epic', and said it's unlike any that's ever aired before. 

'It's crazy,' she said. 'I can't even explain how good it is ... I don't know if us or any other Housewives franchise can top it.'
