The No Doubt singer met her second boyfriend Gavin Rossdale when she was touring with his band Bush in 1995.
They got married on the 14th September 2002 in St Pauls, Covent Garden, London.
The pair had another wedding in Los Angeles just two weeks later all so Stefani could wear her John Galliano custom-designed wedding dress twice.
In 2004, a paternity test revealed that Rossdale had a daughter Daisy Lowe from his pervious relationship with Pearl Lowe.
According to the press Stefani was ' devastated and infurtiated' (Wikipedia) and their relationship consequently suffered.
Stefani is now Daisy's godmother and allegedly has a healthy relationship with her. Perhaps this prompted her to want to take some time out from her music; 'I really want to take some more time out and be with my husband. I guess what I really want is to have a baby. Life is short and you've got to get the most out of it.' (IMDB)
In December 2005, the couple announced that they were expecting their first child. US Weekly found out when Stefani said "I want you to sing so loud that the baby hears it!" while in a concert in Fort Lauredale, Florida. (Wikipedia)
Their first son, Kingston James McGregor Rossdale was born on the 26th May 2006.
Stefani's father in law let the cat out of the bag and revealed that the couple were expecting their second child; another son. Zuma Nesta Rock Rossdale was born on the 21st August 2008.
In February 2008, Stefani gave birth to her third child with Rossdale; Apollo Bowie Flynn.
On 3rd August 2015, Stefani filed for divorce from Rossdale citing 'irreconcilable differences'.
