We've already mentioned how to meet The Bachelor stars at Red Cross blood drives across the country during National Blood Donor Month. The first big event was held Saturday in the Los Angeles area and a clown car of Bachelor folks unloaded at the event. We spotted Rosemaster Chris Harrison, redux Bachelor Brad Womack, "guard and protect" Bachelorette suitor Kasey Kahl, Bachelor Pad hottie Krisily Kennedy, Bachelor Pad supercouple Kiptyn Locke + Tenley Molzahn (Kip-Ten!), Bachelorette suitor Juan Barbieri, Season 4 Bachelorette DeAnna Pappas and her fiance Stephen Stagliano, Season 7 Bachelor Charlie O'Connell holding a dog (?) and Season 7 bachelorettes Kara Smith and Anitra Mohl. Bachelor Pad winner Natalie Getz and Jake Pavelka's former love Vienna Girardi also showed up — see our cute photos that prove it!
