Pop diva Gwen Stefani and her rock-star husband Gavin Rossdale are expecting their second child, family members confirmed to US media on Tuesday.

Now People magazine confirms speculation via a statement from Gavin’s father.

“They and the whole family are delighted,” Douglas Rossdale tells PEOPLE exclusively.

According to Britain’s The Sun, the singer is 13 weeks into her pregnancy, meaning her 1-year-old son Kingston will have a sibling by summer’s end!
