Gwen Stefani's father-in-law has left no doubt as to the cause of her slightly burgeoning belly.
After a few weeks of mild speculation (with all due respect, Gwendale's no Brangelina), Gavin Rossdale's father has confirmed that his rocker son and the Harajuku-loving Stefani are expecting their second child together.
"They and the whole family are delighted," Douglas Rossdale told People.
The elder Rossdale did not reveal a due date or sex of the forthcoming baby.
Reps for the duo are less loose-lipped than the once and future grandpa and have not yet confirmed that a storkwatch is in effect.
News of the Grammy winner's expectant state comes the same day Britain's Sun tabloid published a report claiming the singer was 13 weeks pregnant with a second child.
Last summer, the singer told InStyle that plans for another baby were already in the works.
"Obviously I'm in a race to have another, but I don't want to do it while on tour," she told the magazine. "But I can't wait to get pregnant again. It's so fun and consuming and romantic."
There's no word on whether Stefani's gestation period will in any way interfere with previously announced plans to reunite with No Doubt later this year. The Orange County, California-bred group has announced plans to release a new album and had been expected to begin recording sometime this year.
The 38-year-old platinum-haired songbird tied the knot with the 40-year-old former Bush frontman in London in September 2002. The duo has one child together, son Kinsgston James McGregor Rossdale, who formally enters his terrible twos on May 26.
Rossdale also has a 18-year-old daughter, Daisy Lowe, whom he discovered was his back in 2004.
Of his latest grandchild, Douglas Rossdale told People that Kingston was "a great lad."
"And we are very much looking forward to another grandchild."
