Vanessa shopping for her sis!

Vanessa Hudgens goes shopping for her younger sister Stella’s birthday in Studio City on Monday with mom Gina. The High School Musical star stopped at Baskin Robins where she picked out a cute-looking cake for her Stella. She then picked up gifts at Best Buy and Target including a swivel 19-inch monitor. Stella turns 12 tomorrow (Tuesday). HAPPY BIRTHDAY, STELLA! P.S. Yes, she is wearing boyfriend Zac Efron’s beanie again!
