I stopped by The Talk this week for a conversation about why girl groups are on the decline these days — and with guest hosts Mel B [1] of the Spice Girls and Carnie Wilson of Wilson Phillips, the topic couldn't have been more fitting. Watch to see what Mel B had to say about a 20-year reunion for the Spice Girls — she admitted "there's always one" holdout but gave fans hope that something exciting is in the works!
