Gwen Stefani and Gavin Rossdale's celebrity neighbors are on high alert after a gang of burglars attempted to break into the couple's London home.

The door to the couple's $6.4 million house in Primrose Hill was smashed open on Saturday night at approximately 11.30pm local time, according to Britain's Daily Mail newspaper. Local authorities were alerted on Sunday after a passer-by noticed the damaged entrance.

The robbers broke into and stole jewelry from the couple's tenant in the ground floor apartment. However, thieves were unable to break into the upstairs home shared by Stefani, Rossdale and their two children - Kingston, three, and Zuma, one. Police sources say the burglars were thwarted because the couple's home is a "very secure venue."

No Doubt singer Stefani was playing a concert in Singapore with Beyonce and the Black Eyed Peas when the incident occurred.

Stefani and Rossdale's neighborhood is also home to James Bond star Daniel Craig and celebrity chef Jamie Oliver.
