People.com Celebrity Parents Brooklyn Decker and Andy Roddick's Son, 3, Wore a 'Wildly Inappropriate' Costume on Halloween "He called it a nice monster but he really was a demonic pumpkin," Brooklyn Decker joked to PEOPLE of her 3-year-old son's Halloween costume By Kristen O'Brien Published on November 5, 2018 02:15 PM Share Tweet Pin Email Halloween this year was a very spooky occasion for the Decker-Roddick clan. Son Hank, 3, went trick-or-treating for the first time and was in charge of choosing the costumes, including for his parents Brooklyn Decker and Andy Roddick. PEOPLE heard the tale firsthand at Thursday night’s 13th Annual Andy Roddick Foundation Gala in Austin, Texas, where the former tennis champion, 36, and actress and entrepreneur walked the red carpet. Dierks Bentley also performed at the event to raise money for the foundation, which provides after-school and summer programs for children and families in need. “We were in Charlotte visiting my parents so this was Hank’s first time trick-or-treating,” Decker, 31, told PEOPLE. “He was a combination of things. He called it a nice monster but he really was a demonic pumpkin.” Suzanne Cordeiro/REX/Shutterstock “It was wildly inappropriate for a 3-year-old,” added the mother of two. “It was this terrifying adult mask, which he wanted because he saw it as a nice monster.” Want all the latest pregnancy and birth announcements, plus celebrity mom blogs?

But Hank didn’t stop at picking out his own costume — he wanted a say in choosing what his parents would wear. “I was a bearded witch,” said Decker. “And he had Andy as this terrifying clown. But everyone was really disturbing.” “It was like a freaky clown mask but it had a smile so his little 3-year-old mind processed that as a happy one,” added Roddick. Andy Roddick.

They’ll still split time between L.A., Austin and North Carolina, but Decker — who also shares 11-month-old daughter Stevie with Roddick — looks forward to being able to “stroll with the kids around Lady Bird Lake, enjoy all the food and live in Austin the way it’s meant to be lived.”
