"Look who stopped by rehearsal! @loriloughlin @andreabarber @markballas #dwts @dancingabc," Cameron captioned the pic.
The reunion carried on to Monday, as Barber took to her Instagram account to share a photo of herself posing alongside Scott Weigner (Cameron's love interest in the 90s sitcom) on Monday.
"Got me a hot date for the ballroom tonight. Shhh...don't tell Deej! @scottweinger #DWTS," Barber wrote in the caption.
