OK! Exclusive: Watch Jessica Alba's Awkward Encounter With Sara Foster On VH1's Barely Famous

We've already told you about our favorite new show called Barely Famous, VH1's new docu-series comedy that follows the daily lives of the two sorta-famous Foster sisters in LA. And while the girls—whose dad and stepmom are RHOBH's David and Yolanda Foster— realize that they themselves are not exactly A-Listers, they have a lot of super famous friends who will make appearances throughout the entire season. Last night's premiere had a nice cameo from Nicole Richie, and the second episode features none other than Jessica Alba!
