Britney Spears celebrates her sons

While she is back on the right track, Britney Spears is throwing parties for her sons, to celebrate their birthday. Preston and Jayden had this Saturday a birthday bash with cars and trucks, and all their family.

Spears celebrated her boys’ special days – Preston turns 3 on Sept. 14, and Jayden turned 2 on Sept. 12 – with her younger sister and her newborn niece Maddie Briann, dad Jamie and mom Lynne.

The baby paty gathered around some famous babies of course, along with their more famous parents:  Jenny McCarthy with her son Evan, and Gwen Stefani’s son Kingston, 2, who came to the bash from an equally starry affair: He celebrated Heidi Klum’s son Henry’s 3rd birthday at the model’s Beverly Hills house along with all three of Victoria Beckham’s sons.

The two Spears kids had mini motorized cars to drive around, specially customized Ed Hardy by Christian Audigier. The cars featured tattoo-inspired decals, Ed Hardy air fresheners and personalized license plates. To keep with the party’s theme, the cake was in shape of a yellow truck.

“The boys received tons of birthday gifts. Britney and her family really made the party special for the boys”, a source declared about the party.
