On Monday afternoon the 44-year-old No Doubt singer went to her acupuncture appointment in Los Angeles, and from her crimson lips to her strappy red sandals, her look was pure perfection from head to toe!

Gwen still hasn't revealed why she goes to acupuncture so often, but yesterday she broke the news that hubby Gavin Rossdale will be joining her as a mentor for Team Gwen on The Voice!

"This fall, honored to be part of #TheVoice w/ the lovely & talented @gwenstefani," Rossdale tweeted, while Gwen added an Instagram photo of the couple and wrote, "It's official! so excited to have @GavinRossdale on #TeamGwen gx." Gwen is taking over for Christina Aguilera next season, as the pop star is expecting a daughter with fiance Matt Rutler. But just one? We feel like she'll be around longer than that...
