Fire engine limo was the birthday treat for Christina Aguilera’s son on his second birthday

Christina Aguilera decided to push the boat out for her son Max’s second birthday party and treated the toddler to a ride in a fire engine limo, and invited some A-List stars along to share the experience.

The guest of honour onboard the fire-fighter’s truck was the same colour as the limo itself, the giant red puppet Elmo from kid’s TV show Sesame Street. Two-year-old Max Bratman sat on his famous mother’s knee as the fire engine limo took the party group on a spin around the block. A balloon artist also came along for the ride, he kept the youngsters entertained making balloon animals during the fire engine trip.

No Doubt singer Gwen Stefani also boarded the novelty limo along with her three-year-old son, Kingston and one-year-old son Zuma. Christina and Gwen have said to have struck up a strong friendship of late, often meeting up with their children who have also become big pals.

Christina Aguilera spoke out in a recent interview about how motherhood has changed her for the better, saying the experience has changed her for the better. The Genie in a Bottle singer also revealed that her son is the inspiration behind her new album, entitled Bionic which is due for release in March.
