London: Singer Gwen Stefani spent $15,000 on her son`s birthday party, which was attended by stars like Kate Beckinsale and David-Victoria Beckham.
Stefani and her husband Gavin Rossdale celebrated their son Kingston`s fourth birthday at their home in Los Angeles, reports a news website.
Though the couple admits that they hope to add a daughter to their family, but insist they don`t have immediate plans.
"Having two boys - there`s a lot of energy. I mean, it does seem weird that I don`t have a girl, I feel like I`m running out of time," said Stefani.
"I don`t want to spread myself so thin that I can`t be good for them. I`m not focusing on it right now, but it`s not up to me anyway, you know? These things are miracles, so we`ll see," she added.
