Liam and Stella McDermott Get the Giggles!
Gotcha! Stella Doreen McDermott swings in — with a little help from dad Dean — to surprise brother Liam Aaron, 2, on Sunday in Malibu.
After getting their giggles out, the family, including mom Tori Spelling, headed over to the Malibu Lumber Yard to attend the EB Medical Research Foundation picnic, hosted by Courteney Cox-Arquette.
