Lauren Conrad and Frankie Delgado were together in LA yesterday for a hike in Runyon Canyon. LC tweeted about Frankie's weighted vest — see what she and other celebs were up to in our weekly Twitter roundup! Frankie and LC caught up during their exercise session after bonding at The Hills finale. She brought a girlfriend along, though, to go casual for a recent shopping session. While LC and Frankie's show is over for good, she's looking forward to the new Jersey Shore tonight and is hoping Lo Bosworth gets home in time to watch.
