The 28-year-old actress got her first big acting break with the drama and will now again appear on a special segment for Fox network's 25th anniversary, reported Daily Mail online.
Kunis played Jackie Burkhart in the series, which followed the lives of a group of teenage friends living in a fictional town from 1976 to 1979. However, it's unlikely that the actress would have sported any of her former alter-ego's colourful outfits for the recent taping.
The reunion will feature Kunis and Kutcher, alongside former cast mates Valderrama and Laura Prepon reminiscing about their time on the series, which aired from 1998 to 2006 and launched their careers. The two-hour anniversary special will also feature the casts of 'In Living Color', 'Ally McBeal', 'Beverly Hills 90210' and 'The X-Files'.
