It's like Halloween [1] in November! Fergie [2], who is of Mexican descent, just made our hearts melt with this adorable Instagram photo of her 2-year-old son, Axl, celebrating his daddy Josh Duhamel [3]'s 43rd birthday in a firefighter costume. "Let's fire it up for your birthday daddy!!!" the 40-year-old singer, who shares lots of cute family moments [4] with her followers, captioned the photo. Axl is obviously the perfect combination of his beautiful parents — just look at his blond hair, bright eyes, and mischievous smile.
