It doesn't take a Big Brother legend to know that Zach Cornell should have used his secret veto power to keep himself safe this week, but that didn't stop Janelle Pierzina from weighing in on the most shocking move of Big Brother 27 so far. "It's a pretty dumb move," Janelle, 45, told Us Weekly exclusively on Wednesday, August 13, the day before Zach's eviction, as part of her partnership with GamblingSites.com. On the season's opening night, Zach, 27, won $10,000 as part of a competition. What his fellow houseguests didn't know is that the money also functioned like a second Power of Veto.
