Gwen Stefani blonde studio santa monica Some starlets like Rihanna are constantly changing up their look, but not Gwen!

Miss Stefani headed to another recording studio session on Thursday, and the No Doubt lead singer sported her signature bold red lips, leather pants, and a simple white tank. Can you believe she has two kids?! The 42-year-old is pin thin!
