Cake! The Jumpitz! After missing his birthday party the previous weekend due to a high fever, Tori Spelling and Dean McDermott’s son Liam was treated to a car-themed encore on Sunday. Together with his mom, dad, 9-month-old sister Stella and 16 party guests, Liam celebrated his second birthday at his new home outside Los Angeles with the help of toys from the movie Cars, a car-shaped cake (from Beverly Hills bakery Hansen’s Cakes) and a performance by his favorite music group, The Jumpitz. “Liam is obsessed with the animated movie Cars,” says his mom, “and I made him a little red car racing jumpsuit with a Liam name patch on it.” Liam and his friends also enjoyed a blow-up ball pit in his living room and a small petting zoo in the backyard. The Jumpitz, a five-member children’s performance group, helped the intimate group sing “Happy Birthday” to Liam before the cake cutting. Says Spelling: “The cutest was when he got to dig his hands into the giant red car cake and Stella was right into it as well!” At the end of the two-hour shindig, guests left with gift bags by Silver Spoons! – each with personalized bag tags by Mabel’s Labels.
