Gwen Stefani has been recommending acupuncture to her pals after it helped her with severe migraines during her pregnancy.
The 44-year-old mother-of-three started having the treatment after getting severe migraines while pregnant with her third son, Apollo, and has told all of her friends to try it.
A source told RadarOnline: "Gwen started doing acupuncture to get rid of the severe migraine headaches that she gets during her pregnancies. All moms are doing it."
"She loves it and shares it with all her mommy friends because of how much it has helped her on so many levels."
Gwen also has sons Kingston, seven and five-year-old Zuma with husband Gavin Rossdale.
Meanwhile, the busy star recently revealed she will make a comeback to New York Fashion Week this September.
The No Doubt singer is adamant she hasn't turned her back on her clothing line, L.A.M.B., and has only been absent from the fashion event in recent years because it clashed with her commitments to her young sons.
She told ELLE.com: "I am going to do some sort of presentation or show this September. The only reason I haven't lately is because it falls when my kids go back to school and I was like, 'Oh, I guess I will go to NYFW and miss my kid's first day of kindergarten.' No.
"This year it falls on a different week so I can be in both places."
