[Sienna Miller and Rachel Nichols on the Wall Street trading floor. Photos via Getty]. Celebrities and B-listers are busy, busy this week, trying to be active members of society. Sienna Miller and Channing Tatum were ringing the opening bell on Wall Street, Ashlee Simpson was trying out her red look at the Showtime TCA party, and Jon Gosselin was raising some of his children. I wonder if he is missing his GOHAN days. Speaking of bromance, Clooney and Rande Gerber hit the road this weekend, a dangerous activity compared to the beach frolicking of AnnaLynne McCord.
