Pop star Gwen Stefani insists breastfeeding helped her lose weight after having her baby because it gave her lots of extra energy. The 37-year-old star gave birth to son Kingston in May and was desperate to get back to her normal size.

Stefani explains, "I'm still nursing, and I think it gives you superhuman powers."

She admits she was obsessed about getting her body back in top form adding, "That was one of the hardest things for me - the pressure of, 'OK, I need to get into shape so that I can put this record out.' If I didn't have that pressure, I don't think I would have gotten the baby weight off so quickly!"
