Roseanne Barr is returning to TV comedy - as funny woman Chelsea Handler's aunt.
 
Barr has joined Laura Prepon in the TV sitcom adaptation of Handler's book "Are You There Vodka, It's Me, Chelsea."
 
Prepon will play Chelsea Hanson - a character based on Handler - in the series.
 
She's not the only former "That 70's Show" star returning to a starring role on TV; Ashton Kutcher has signed on to replace Charlie Sheen in sitcom "Two and a Half Men."
