Video: Katy Perry's First Post-Split Red Carpet

Katy Perry stepped out on a red carpet on Friday night, for the first time since her split from husband Russell Brand.
Katy posed with her pal, jewelry designer Markus Molinari, at the event at 1 Oak club in Las Vegas which benefited, an organization which supports community-led sanitation projects in Haiti.
Markus told that Katy had joined in the event because "that's what friends do" and said that she's doing "amazing."
Meanwhile, Russell Brand was spotted Saturday attending a Kundalini yoga class at Golden Bridge Yoga in Los Angeles, California.
Russell filed for divorce from Katy shortly after Christmas.
