Kingston Rossdale is a Balloon Baby

Gwen Stefani and husband Gavin Rossdale spend some quality time out with their son Kingston and his balloon in a park in Beverly Hills on Sunday.

The 39-year-old singer’s Harajuku Lovers perfume line was promoted in Toronto and Montreal this weekend where samples were handed out with Gwen‘s music blasting in the background!

Leslie Oglesby, the Global Marketing Director for Gwen Stefani Fragrances said, “Gwen is amazing and totally down to earth, like talking to your sister. She’s passionate about her fragrance line and is very easy to work with!”
