Little Sean Preston, 3, oldest son of Britney Spears spent last weekend with his new baby cousin, Maddie Briann, daughter of Jamie Lynn Spears. Sean and baby brother Jayden James, 2, celebrated their birthdays with mom and extended family. Obviously Sean is quite taken with the newest family member! Smooches!
Couple more pics after the jump!
Brit threw a truck-themed party for her sons last Saturday - Jayden turned two on September 12 and Sean turned three on September 14. Adorable kids!
