Jennifer Lopez and Marc Anthony's twins are now 1-year-old, and to celebrate, the parents threw a big b-day bash at their house in Bel-Air yesterday. Looks like they went all out, too! Guests included manager Benny Medina, and others were seen carrying in Elmo and Disney bags filled with presents! Check out the gallery to find out more...
