The Real Housewives of Beverly Hills might be expanding their cast with beauty Christine Chiu, and according to an insider it will be the THIRD time Bravo has tested her for the hit show, Breaking Celebrity News is exclusively reporting.

Chiu, wife to acclaimed plastic surgeon to the stars, Dr. Gabriel Chiu, is toying with the idea of joining the ladies in the 90210 but Bravo execs are still figuring out if she's a good fit.

"Christine is definitely in the running to join the Real Housewives of Beverly Hills," the source told Breaking Celebrity News.

"She has the lifestyle producers are looking for, but there's something holding them back because this is the third season they've tested her for."

Chiu was spotted filming at the Vampire Lounge & Tasting Room last week with Brandi Glanville — maybe a preview of what's to come? -- but that's not her only connection to the RHOBH cast; her husband is good friends with Adrienne Maloof's ex-hubby, Dr. Paul Nassif.
