It's a family affair in this episode of "Dr. 90210" as some deserving moms are given the gift of beauty from their kids! For adult film star (and repeat "Dr. 90210" patient) Tabitha Stevens, going under the knife has become so common that her doctor has refused to operate on her! (Well, at least for the time being.) And now the tables are turned as Tabitha's mom opts for a little nip and tuck (tummy tuck, natch!) and some liposuction to help her kick start a new chapter in her life. Can Dr. Manus help give her the flat stomach she's always dreamed of? Or will her health issues pose a problem in the operating room? Meanwhile, Dr. Kirby is pushing for the "Son of the Year" award as he turns his mother into one hot mama, courtesy of a liquid facelift and chemical peel. Also, Dr. Alter helps a 49-year-old virgin uncover his hidden penis, but is he willing to pay the price when it leads to life-threatening complications? Stay tuned!
