Looks like Bachelor 17 winner Catherine Guidici has become fast friends with Sean Lowe's fellow castmates on Dancing With The Stars! In case you'd forgotten (read: blocked it out) Sean is currently sashaying his days away alongside a bunch of A-listers, and his sassiest former co-star, Lisa Vanderpump, recently hosted Catherine's birthday party on April 28!

Catherine spent the night before her soiree hanging with Pandora Vanderpump (Lisa's daughter) and songstress Scheana Marie, and then hit up Lisa's Los Angeles restaurant, Villa Blanca, on her actual birthday for a decadent meal. The guest list? None other than Lisa, Pandora, Scheana, producer Mike Shay (who appears on Lisa's show Vanderpump Rules), and of course Catherine's mom — who flew in from Seattle for her baby gal's big day!

It appears as though Beverly Hills Lifestyle Magazine was there to capture the event, and duh –– Catherine had an absolute blast. "I am blessed," she tweeted on April 29. "#birthdaydinner."

No word yet as to what Sean gave his wifey-to-be for her birthday, but we can only assume Catherine was treated to a rated-G striptease. Hopefully Chris Harrison had a hidden camera installed in their apartment to capture the moment. Blooper reel, anyone?
